Answer:
The answer is D
Step-by-step explanation:
F(5) = 3x(5)^2 - 5 = 3x25 - 5 = 75 - 5 = 70;
f(4) = 3x(4)^2 - 5 = 3x16 - 5 = 48 - 5 = 43;
f(x) + g(x) = 3
We can use the equation y=2(0.0625)+5(0.125), y being the thickness of the plywood.
I got 5(0.125) because two sheets of the 7 were already used, meaning there are 5 sheets of plywood left over.
y=0.125+0.625
y=0.75
Therefore, the plywood is 0.75 inches thick.
