Answer 1

Answer:

D) 16x^2 + 4x

Step-by-step explanation:

So a since there is two lengths and two height, you are gonna have to add them all up.

5x^2 + 2x + 5x^2 + 2x + 3x^2 + 3x^2

(See why I put the length value and width value twice? Because there is two of each.)

Now start adding up common factors. Let's start with any x^2

10x^2+2x + 2x + 6x^2

I added up the 5x^2 together to get 10x^2 and I added the 3x^2 together to get 6x^2, now you are gonna add those two up

16x^2 + 2x + 2x

(Just from looking at this, you can easily cross out answers A and B)

Now add the x together

16x + 4x

So the the answer is D
