Ab+bc=
this is adding of like terms

(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.

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
