Answer:
3x+7
Step-by-step explanation:
Use long division or synthetic division. (3x^2+13x+14)/(x+2)
The length of the rectangular garden is 3x + 7
The given expression:
[tex]A = 3x^2 + 13x + 14[/tex]
the width of the garden = x + 2
let the length of the garden = y
To find:
the length of the gardenThe area of the rectangular garden is calculated as;
[tex]A = y(x + 2) = 3x^2 + 13x + 14\\\\y(x + 2) = 3x^2 + 13x + 14\\\\y = \frac{3x^2 + 13x + 14}{x + 2}[/tex]
Using long division method:
3x + 7
------------------------------
x + 2 √ 3x² + 13x + 14
- (3x² + 6x)
-------------------------
7x + 14
- (7x + 14)
-------------------------------
0
Thus, the length of the rectangular garden, y = 3x + 7

Answer:
[tex]CD = 12.6866616739cm[/tex]
[tex]CD \approx12.7cm[/tex]
Step-by-step explanation:
[tex]CB = a[/tex]
[tex]AB = b[/tex]
[tex]AC = c[/tex]
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
[tex] {a}^{2} = {c}^{2} - {b}^{2} [/tex]
[tex]a = \sqrt{ {c}^{2} - {b}^{2} } [/tex]
[tex]a = \sqrt{ {12}^{2} - {6}^{2} } [/tex]
[tex]a = \sqrt{144 - 36} [/tex]
[tex]a = \sqrt{108} [/tex]
[tex]CB = \sqrt{108} [/tex]
[tex] \sin(D) = \frac{opposite}{hypotenuse} [/tex]
[tex] \sin(D) = \frac{CB}{CD} [/tex]
[tex] \sin(55) = \frac{ \sqrt{108} }{CD} [/tex]
[tex](CD) \sin(55) = \frac{ \sqrt{108} }{CD} (CD)[/tex]
[tex](CD) \sin(55) = \sqrt{108} [/tex]
[tex] \frac{(CD) \sin(55) }{ \sin(55) } = \frac{ \sqrt{108} }{ \sin(55) } [/tex]
[tex]CD = \frac{ \sqrt{108} }{ \sin(55) } [/tex]
[tex]CD = 12.6866616739cm[/tex]

Please help
Due asap SHOW a workings please
Answer:
A
Step-by-step explanation:
1) first there are a few rules we need to know:
a) the sum of any two sides of a triangle is always larger than the 3rd side
b) the difference between any two sides of a triangle is always smaller than the 3rd side;
hence,
3+4=7
4-3=1
triangle 3,4,5 follows all the rules,
triangle 13,2,11:
11+2=13
the sum of any two sides must always be GREATER than the 3rd side-so this is not an option
triangle 10,4,5
5+4=9
9<10
not an option

Answer:
90
Step-by-step explanation:
a triangle's angles all add up to 180. take 51 and 39 away from 180 and you get 90
Answer: 90 degrees
Step-by-step explanation:
Theorem:
a+b+c=180 degrees
39 degrees + 51 degrees + x degrees = 180 degrees
39 + 51 = 90
180 - 90 = 90
A saving account earns 4.5 simple interest per year. If 650.00 is deposited and no withdrawals or deposits are made during one year how much interest will be earned after one year
Answer:
29.25 Interest
Step-by-step explanation:
Take the formula: I=PRT
The principal is 650.00, 4.5 is the rate, 1 year is the time, We do not know the interest.
Change the rate, 4.5 to 0.045 to help solve the problem.
Times 650.00, 0.045, and 1 together.
You will get 29.25, Which is the answer!
Booyah! You are done.

5x+2=7x-4. Plz answer my question
Answer:
x=3
Step-by-step explanation:
5x+2=7x−4
5x+2−7x=7x−4−7x
−2x+2=−4
−2x+2−2=−4−2
−2x=−6
-2x/2=-6/2
x=3
Solve this system
5x – 4y + 2z = 21
-x - 5y + 6z=-24
--x – 4y + 5z =-21
O x = 5, y = -1, z = -4
0 x = 1, y = 5, z = -4
O x=-5, y = 1, z = -4
O x = -4, y = -1, z = 5

Can someone help me understand this
Answer:
Step-by-step explanation:
If we define the line QR to be some variable of distance 'x', we can use the relationship of cosine to figure out the length of QR.
Remember, cosine is adjacent of the angle divided by the hypotenuse of the angle. So, if we take this x value over the longest side (hypotenuse), we get the value of cos(theta).
cos(25) = x/7
Multiply both sides by 7 to get:
7*cos(25) = x
Let your calculator do the work to get:
x = 6.3

All of the following are equivalent except____.
4y
(4)(y)
4•y
4+y
Answer:
All the options are equivalent except;
4 + y
Step-by-step explanation:
The question relates to the number of ways the operation of a multiplication operation can be represented algebra
1) The coefficient of a variable is a multiplier of the variable
Therefore;
4y = 4 × y
2) When given two numbers or variables in a mathematical expression that are separated by parenthesis, then it is an indication that the two numbers are meant to be multiplied
Therefore;
(4)(y) = 4 × y
3) The dot symbol, '·', placed between two numbers, a number and a variable or two variables, is a representation of multiplication of the two quantities
Therefore;
4·y = 4 × y
However, multiplication, and addition are different mathematical operations that produce different results when applied;
Therefore;
4 + y ≠ 4 × y.
