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.
<u>5x^2 + 2x</u> + <u>5x^2 + 2x</u> + <u>3x^2</u> + <u>3x^2</u>
<u>(</u>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
Answer:
4000
Step-by-step explanation:
divide 1.5% by 100 to remove the % symbol: 0.015
set you equation: 0.015x = 60
divide both sides by 0.015: x = 4000
