Answer:
y = - 2x² - 2x + 40
Step-by-step explanation:
Standard form of a quadratic is y = ax² + bx + c : a ≠ 0
Given
y = - 2(x + 5)(x - 4) ← expand factors using FOIL
= - 2(x² - 4x + 5x - 20)
= - 2(x² + x - 20) ← distribute parenthesis by - 2
= - 2x² - 2x + 40 ← in standard form
To solve this problem, we need to know the formula of the surface area of a triangular prism. The formula is: A = 2

+ (a+b+c) * h
Now we can substitute values and solve
A = 2(0.5 * 4 * 3) + (3+4+5) * 20
A = 12 + 240
A = 252
That means that the answer to this question is 252 square feet.
