Answer:

(a+c)b OR it's already on simplified form

Step-by-step explanation:

depending upon what your instructor wants, they may want you to say it's already simplified (which happens sometimes).

HOWEVER, if you know how to factorize (which is essentially un-distributing), you could factor out the b which is common in both.

$ab + bc \\ = b( \frac{ab}{b} + \frac{bc}{b} ) \\ = b(a + c)$

f(x)=10x+8

g(x)=1x+4 = x+4

(f+g)(x) = f(x) + g(x) = 10x+8+x+4 = 11x + 12

(f+g)(3)= 11(3) + 12 = 33 + 12 = 45

hope that helps
