F(x)·g(x) = (3x +4)·(5 -x) = -3x^2 +11x +20
(f·g)(x) = -3x^2 +11x +20
Hello!
Question 1
3x + 6 = 24
Subtract 6 from both sides
3x = 18
Divide both sides by 3
x = 6
The answer is 6
------------------------------------------------------------------------------------------------------
Question 2
x/4 + 1 = -5
Subtract 1 from both sides
x / 4 = -6
Multiply both sides by 4
x = -24
The answer is -24

Hope this helps!
