given the functions: f(x) = x+4 and g(x) = x-3 what is (f*g)(x)? A. x2+3x+12 B. x2+x+12 C. x2+4x-12 D. x2+x-12

D.  x^2 + x - 12.

Step-by-step explanation:

(f*g)(x) = (x + 4) * (x - 3)

= x(x - 3) + 4(x - 3)

= x^2 - 3x + 4x - 12

= x^2 + x - 12.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
