Answer:
44
Step-by-step explanation:
f(x) = -7x + 5x^2 + 10
f(-2) = -7(-2) + 5(-2)^2 + 10

The area of the room = (40 x 24) - (20 x 12)
Area = 960 - 240 = 720 square feet
Divide square feet by width of a strip:
720 / 12 = 60 linear feet.
The answer is D.
Change 1 1/2 into a improper fraction. then multiply across. so 2 times 3 over 7 times 2. which equals 6/14. then simplify to get 3/7 as your final answer.
