Which of the following best describes the expression 9(x + 7)? a. the sum of constant factors 9 and x + 7 b. the product of constant factors 9 and x + 7 c. the product of a constant factor 9 and a 2-term factor x + 7 d. the sum of a constant factor 9 and a 2-term factor x + 7

C. The product of a constant factor 9 and a 2-term factor x + 7 .

Step-by-step explanation:

Given  :  9(x + 7).

To find : Which of the following best describes the expression .

Solution : We have given that 9(x + 7)

We can see it is a product of 9 and (x+7)

The best description for expression is

Therefore, C. The product of a constant factor 9 and a 2-term factor x + 7 .

(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
