Step-by-step explanation:
12 = 2 × 2 × 3
18 = 2 × 3 × 3
56 = 2 ×2 × 2 × 7
Now
Common factor = 2
Remaining factor = 2 × 3 × 2 × 3 × 7
LCM = RF × CF
= 504
hence the lCM of 12 , 18 and 56 is 504...

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
