My answer:
We need to find the total surface area of the building a skateboard ramp without its bottom.
- The Area of the slope: 10.5*25 = 262.5
- The Area of the two triangles: 2 (
) = 168
- The Area of the back: 10.5*7 = 73.5
So the total surface area is: 262.5 + 168 +73.5 = 504 
Hence, the number quarts of paint will mario needs to buy is:
504/85 ≈ 6

Answer:
the answer is A
Step-by-step explanation:
I have a feeling in my genitals
The current area is 15 x 9 = 135 square feet.
He wants to increase both the length and width by X:
Set up an equation:
(15 +x) * (9 +x) = 135 * 2
Simplify :
x^2 + 24x + 135 = 270
Subtract 270 from both sides:
x^2 + 24x - 135 = 0
Use the quadratic formula to solve for x:
-24 +/- √(24^2 - 4(1*-135) / 2*1
x = 4.7 or -28.7
The answer has to be a positive value, so x = 4.7 feet.
