Answer:

A = 160 mm²

Step-by-step explanation:

The area (A) of a rectangle is calculated as

A = bh ( b is the base and h the height )

Given P = 52 and P = 2(b + h) , then

2(b + h) = 52 ( divide both sides by 2 )

b + h = 26 ( substitute b = 16 )

16 + h = 26 ( subtract 16 from both sides )

h = 10

Then

A = 16 × 10 = 160 mm²

Answer:

its: 160^{2}

Step-by-step explanation:

ps: (b=l)

we have  : P=2 [l+w]

and : P= 52mm

so: 52=2(16mm+w)

    52/2= 16mm+w

     26-16=w

   10=w

so: w=10

and we know that:  area= w*l

so:                          area=10*16

so:          area= 160 mm^{2}

Answer:

Jerry is 11.75 years

Step-by-step explanation:

Let us first set up an equation

Let jerry's age be x

4x - 11 = 36 (equation set)

Now we need to slove the equation and find the value of x that is Jerry's age

4x - 11 = 36

Transpose

4x = 36 + 11

4x = 47

x = 47 ÷ 4

x = 11.75 years

Jerry is 11.75 years

Answer:

The answer to this question is graph B

Answer:

Yeah he/she correct I did that too and got it right

Step-by-step explanation:

(-2, -10) and (4, r)

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)    

⇒                                3    =  (r -(-10)) ÷ (4 - (-2))    

                                  3     =  (r + 10) ÷ (6)

                                18    =  r + 10

                        ∴       r      =  8

Checking my answer:  

Finding the Equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

                                ⇒  y + 10 =  3 (x + 2)

To test my answer, I have included a Desmos Graph that I graphed using the information provided in the question and my answer. The line passes through both the (-2, -10) point and (4, 8). So r = 8.

Answer:

im pretty sure #9 is just y=7x... it should be parallel with y=7x-3 since it has y intercept of 0 rather than -3.

Answer:

m and n are parallel because if you add 55 and 125 together you get 180

Step-by-step explanation:

If the lines are parallel, ∠3 = 125 (due to corresponding angles) and 55 + ∠3 = 180 (since angles on a straight line add upto 180).

Seeing this is true,

the lines m and n are parallel.

Answer:

y = 50

Step-by-step explanation:

This requires the alternate interior angle theorem, which states that:

The alternate interior angle theorem states that if two parallel lines are cut by a transversal, then alternate interior angles are congruent.

Since 50 degrees is an alternate interior angle to y, y must be equal to 50 degrees.

So,

y = 50

Answer:

( 5, 3 )

Step-by-step explanation:

I imagine you plug in the given ordered pair to the rule:

( x - 3, y + 9 )

( 2 - 3, 12 + 9 )   ( - is the same as going to the right, so it basically adds ).

                         ( + is the same as going to the right, so it basically subtracts ).

( 5, 3 )

Hopefully this helped!

Brainliest please?

Answer:

using the formula( y2-y1/x2-x1 = m)

m= slope

9 - (-2)/-9 -2 =m

11/ -11 = m

m= -1( slope)

since m is also = y- y1/ x-x1

y - (-2)/ x- 2 = -1= y +2 / x -2 = -1 (cross multipy)

-1 (x -2) = y +2

-x +2 = y + 2

-x -y = 2 -2

-x - y = 0(multiply both sides by -1)

x + y = 0

Answer:

It would be distributive property

Step-by-step explanation:

Because you have parenthesis and you need to distribute that 2 to everything in the parenthesis and you will get 2x+6 because 2(x)=2x and 2(3)=6 and when you put those together you get 2x+6

Answer:

-10

Step-by-step explanation:

1. First, let's simplify both sides of the equation.

2. To find the missing value to make the equation have infinitely many solutions, we need to make both sides of the equation equal.

3. Given that information, means that 4x - 10 has to equal 4x + (-10) because:

4. Now, with the information in #2, let's see if it's true:

Therefore, the missing number is -10.
