To draw the median of the triangle from vertex A, the mid point of BC must be determined. The median of the vertex A is given at (-1/2, 1). See explanation below.

Recall that B = (3, 7)

and            C = (-4, -5).

Connecting D' and A gives us the median of the vertex A. See attached graph.

Recall that
A → (4, 2); and

B → (3, 7)

Hence, the Midpoint will be

[tex][(\frac{4+3}{2} )[/tex], [tex](\frac{2+7}{2} )][/tex]

→  [tex](\frac{7}{2}, \frac{9}{2} )[/tex]

After solving the algebraic expression a(b-c)-b(a+c)-c(a-b) we get the equivalent answer as  ₋2(ab ₊ ac).

What is equivalent of algebraic expression?

Expressions that are equivalent do the same thing even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).

Given the expression is a(b₋c)₋b(a₊c)₋c(a₋b)

The first step is to multiply the terms.

⇒(a×b ₋ a×c) ₋ (b×a ₊ b×c) ₋ (c×a - c×b)

= (ab ₋ ac) ₋ (ba ₊ bc) ₋ (ca ₋ cb)

Now open the brackets.

= ab ₋ ac ₋ ba ₋ bc ₋ ca ₊ cb

Now comes main step of combining the like terms.

Put similar terms together on both sides of the equation.The two phrases are equal if each of the terms in both of them is the equivalent.

= ab ₋ ba ₋ ac ₋ ca ₋ bc ₊bc

Since, bc is a  like term with opposite sign, therefore bc  gets cancelled.

= ab ₋ ba ₋ ac ₋ ca

= ₋2ab ₋ 2ac

Take 2 as a common term from both the terms.

= ₋2(ab ₊ ac)

Hence we get the required equivalent of a(b-c)-b(a+c)-c(a-b) as

Answers:
 1)  The value of AB  is:  " 59 units."
 2) The value of BC  is: "21 units."
_______
 3) The value of AB  +  BC ;

     =   59  units  +   21  units ;

     =   [the value of AC ] ;

     =  {" 80 units ".}.
_______

Step-by-step explanation:                                            

Given the following—and based on the assumption that we are dealing with:  "geometric lines"—and/or: "geometric line segments"—we are asked to:  
  "Find the value of:  " AB and BC" .
    {Given: " AB = (8x + 3) ;  BC  = (2x + 7) ;  AC = 80 ".}.
----------------------------------------------------------------------------------------------=-
Note:  The following "line graphs" are "Not Drawn to Scale."

        |    (8x + 3)     |      (2x + 7)       |

        |<--------------->|<------------------->|

<----·|----------------->|<------------------->|  {Note:  "Not drawn to scale."}.
       A                   B                         C
<-----|----------------->|<------------------->|

       A                                               C

<-----|<--------------------------------------->|  

<-----|----------------------------------------->|          

       A             {"AC = 80 ".}             C

 <---|------------------------------------------>|
       A       {"AC = 80 ".}.                  C

       |  (8x + 3) ;   +       (2x + 7)      =  80 ;  

<-----|----------------->|<--------------------->I
       A                    B                         C

So:  We have to find the value of:
     1) AB ; which is: (8x + 3) ;  And:
     2) BC ;  which is:  (2x + 7) .

To get these values; we need to find the value for "x".

So:   (8x + 3)  +  (2x + 7)   = 80  ;  
      ➝  8x + 3 + 2x + 7 = 80 ;

      ➝ Now, Let us combine the "like terms" on the "left-hand side" of the equation:
    +8x + 2x + 3 + 7  ;

      ➝  to get: + 8x + 2x = + 10x  ; and:
                       +3 + 7 = 10 ;

      To get:  "10x + 10" ;

Now, we can rewrite the equation:
       {" 70 ÷ 10 = 7 ."}.   " 10x + 10 = 80 ;

_____________________
To solve for "x" ; there are many ways:
_____________________
Method 1)  We have:  " 10x + 10 = 80 " ;
 ➝ Now, subtract "10" from each side of the question;
       10x + 10 − 10 = 80 − 10 ;
to get:  10x = 70 ;

 ➝  Now, divide each side of the equation by: "10" ; to isolate "x" on one side of the equation;  & to solve for "x" ;

  10x /10 = 70 /10 ;   to get:  " x = 7 "

Method 2)
 At the moment above in which we have:
" 10x = 70 " ;   we know that "10x ÷ 10 = 1x" ; and then "70 ÷ 10 = 7 ".

       {Note that any value; divided by "10" ;  is equal to:
{"that value" moved Back by:  "One" decimal space.}.  

So:  " 1x = 7 " ; ↔ " x = 7 ".

_____________
Method 3) :

When we have:  " 10x /10 = 70 /10 " ;  we have " 1x " on the "left-hand side" of the equation;  and:  "{ 70 /10 }" = {" 70 ÷ 10 = 7 ."}.

Note that: {" 70 ÷ 10 = 7 "} ; can be determined in many ways;
    For instance: {" 70 ÷ 10 = ? "} ;  

 ➝  The zeros for Both the numerator and denominator "cancel out"—

and we have:  " [tex]\frac{70}{10}[/tex] " ;  
 ➝  Cancel out each of the two (2) "zeros" ; and we have:  " [tex]\frac{7}{1} = 7.[/tex] "

 ➝  This is assuming that we figure out that:  " [tex]\frac{10x}{10}=1x =x[/tex] ."

___________

Now; let's find the correct values for this Brainly Question:
1) AB  =  8x + 3 ;  
Substitute our calculated value for "x" ; and solve:

➝  AB = 8x + 3 ;  ↔  8(7)  + 3   =  56  + 3  = 59 .

➝ BC  = 2x + 7 ;  ↔ 2(7)  +  7   =  14 + 7   =  21 .
Note:
➝  AC  =  80 = AB  + BC   ≟   59 + 21  ≟  80 ?  Yes!

____________
Answers:
 1) The value of AB  is:  " 59 units."
 ___
 2) The value of BC  is:   "21 units."
___

 3) The value of AB + BC  ;

           = 59 units + 21 units  =  {The value of AC }  =  "80 units".}.

Answer:

Jesse will need about 89.5 square inches of gift wrap.

Step-by-step explanation:

We need to find the amount of wrapping paper that will cover the entire outside surface of the cylindrical gift. This means that we need to find its surface area, which is the total area an object's surface occupies.

The formula for cylinder surface area is as follows:

[tex]A=2\pi rh+2\pi r^{2}[/tex] (where r = radius and h = height)

In this case, the radius, or r, is 1.5 in, and the height, or h, is 8 in. Plugging these values into our formula, we get a total surface area of:

[tex]A=2\pi rh+2\pi r^{2}\\= 2\pi *1.5*8+2\pi * 1.5^{2} \\= 24\pi +4.5\pi \\=28.5\pi \\ \approx \text{\bf 89.5 \bf $in^{2}$ }[/tex]

Hope this helps!

Answer:

28.5 pi square inches

Step-by-step explanation:

The surface area of a cylinder is the lateral area plus two times the area of the base circle. The lateral area is the perimeter of the base circle times the height, and the perimeter of a circle is 2*pi*r.

Therefore the lateral area is:

LA = Perimeter*Height

     = 2*pi*r*h

     = 2*pi*1.5*8

     = 24pi

The base area would be A = pi*r*r since the bases of cylinders are circles.

BA = pi*r*r

     = pi*1.5*1.5

     = 2.25 pi

Since there are two circles (top AND bottom) in a cylinder, the final surface area of the cylinder would be:

SA = LA + 2BA

     = 24pi + 2*2.25pi

     = 24pi + 4.5pi

     = 28.5 pi

(a) The inequality follows from the binomial theorem.

[tex](a - b)^2 = a^2 - 2ab + b^2 \ge 0 \implies a^2 + 2ab + b^2 = (a+b)^2 \ge 4ab \\\\ \implies \dfrac{(a+b)^2}4 \ge ab \\\\ \implies \dfrac{a+b}2 \ge \sqrt{ab} ~~~~~~~~ (1)[/tex]

By the same reasoning,

[tex]\dfrac{c+d}2 \ge \sqrt{cd}[/tex]

Adding these results together, we have

[tex]\dfrac{a+b}2 + \dfrac{c+d}2 = \dfrac{a+b+c+d}2 \ge \sqrt{ab} + \sqrt{cd}[/tex]

and since [tex]\sqrt{ab}[/tex] and [tex]\sqrt{cd}[/tex] are both positive, they also satisfy the AM-GM inequality,

[tex]\dfrac{\sqrt{ab} + \sqrt{cd}}2 \ge \sqrt{\sqrt{ab}\times\sqrt{cd}} = \sqrt[4]{abcd}[/tex]

and the 4-variable result follows,

[tex]\dfrac{a+b+c+d}2 \ge 2\times\dfrac{\sqrt{ab}+\sqrt{cd}}2 \ge 2 \sqrt[4]{abcd} \\\\ \implies \dfrac{a+b+c+d}4 \ge \sqrt[4]{abcd} ~~~~~~~~ (2)[/tex]

(b.i) With [tex]m=\frac{a+b+c}3[/tex], we have

[tex]\dfrac{3m}4 = \dfrac{a+b+c}4 \implies m - \dfrac m4 = \dfrac{a+b+c}4 \\\\ \implies m = \dfrac{a+b+c+m}4[/tex]

(b.ii) From (2) it follows that

[tex]\dfrac{a+b+c+m}4 \ge \sqrt[4]{abcm} = \sqrt[4]{abc\times\dfrac{a+b+c+m}4}[/tex]

Using the result from (b.i), this is equivalent to

[tex]\dfrac{a+b+c}3 \ge \sqrt[4]{abc\times\dfrac{a+b+c}3}[/tex]

Take 4th powers on both sides.

[tex]\left(\dfrac{a+b+c}3\right)^4 \ge abc \times \dfrac{a+b+c}3[/tex]

Divide both sides by [tex]\frac{a+b+c}3[/tex].

[tex]\left(\dfrac{a+b+c}3\right)^3 \ge abc[/tex]

Finally, take the cube root of both sides.

[tex]\dfrac{a+b+c}3 \ge \sqrt[3]{abc}[/tex]

⇒ 2.99000000

Get rid of the redundant zeros:

⇒ 2.99

Multiply by 10 to the power of the number of decimal places moved:  

⇒ 2.99 x 10⁸

Therefore, the speed of light using scientific notation is:

By solving a system of equations, we conclude that Kelli's speed on still water is 6.1km/h

Let's say that the speed of Kelli in still water is S. And we know that the speed of the river is 5km/h.

When she swims upstream, her velocity is:

(S - 5km/h)

When she swims downstream, her velocity is:

(S + 5km/h)

With the given information, we can write for a distance D:

(S - 5km/h)*1h = D

(S + 5km/h)*6min = D

First, let's rewrite 6 minutes into hours.

1 hour = 60min

6 min = 6/(60) hours = 0.1 hours

Then the system of equations that we need to solve is:

(S - 5km/h)*1h = D

(S + 5km/h)*0.1h = D

D is the same distance in both cases, then we can write:

(S - 5km/h)*1h = (S + 5km/h)*0.1h

Now we can solve this for S.

S*1h - 5km = S*0.1h + 0.5km

S*1h - S*0.1h = 5km + 0.5km

S*(0.9h) = 5.5km

S = 5.5km/0.9h = 6.1km/h

Kelli's speed on still water is 6.1km/h
