Answer:
g(f(3)) = 0
Step-by-step explanation:
f(x) = 2x - 9
f(3) = 2(3) - 9
f(3) = -3
g(-3) = 9 - (-3)^2
g(-3) = 9 - 9
g(-3) = 0
1) If the coefficent of any variable is zero then the answer of the variable is 0.
2) There are two answers in a system of equations.
12 sq units
height = 3
length = 4
A = l · w
A = 12
