Answer:
(A/21h) -c
Step-by-step explanation:
A= 21h(c+d)
A/21h = c+d
(A/21h) -c =d
Answer:
B) -4
Step-by-step explanation:
To solve g(f(3)), we first have to solve f(3):
Since f(x) = -x +4 , f(3) = -3 + 4 = 1
Now we have to solve g(1) , since that is what f(3) left us;
Since g(x) = x^2 - 5 , g(1) = 1^2 - 5 = 1 - 5 = -4
I am sorry math is not my strong suit
