Can someone answer both of these

7) c(h) = 35h + 40

8) $215

answer: a.   one is a factor of every whole number since every number is divisible by itself.

(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
