Answer:
To calculate what you need, multiply the walkway's width and length to find the square footage.
Step-by-step explanation:
To calculate what you need, multiply the walkway's width and length to find the square footage; for example a 4-foot-wide, 50-foot-long walkway covers 200 square feet. Next, factor in the thickness: 4 inches converts to 0.33 feet; multiply this by the square footage to find the cubic feet: 200 x 0.33 = 66 cubic feet.

Answer:
-125
Step-by-step explanation:
Step 1: Find g(-1)
g(x) = -5x²
g(-1) = -5(-1)²
g(-1) = -5(1)
g(-1) = -5
Step 2: Find g(-5)
g(-5) = -5(-5)²
g(-5) = -5(25)
g(-5) = -125
