Answer:
g(f(- 2)) = 91
Step-by-step explanation:
Evaluate f(- 2) then substitute the value obtained into g(x), that is
f(- 2) = - 2 + 7 = 5 , then
g(5) = 4(5)² - 9 = 4(25) - 9 = 100 - 9 = 91

Answer:
2x²+x-15=0
Step-by-step explanation:
A=L×W
12cm²=(2x+3)(x-1)
12=2x²-2x+3x-3
12=2x²+x-3
2x²+x-3-12=0
2x²+x-15=0
