If you round 23.19 to the nearest whole number you get 23 and if you round 13.7 you get 13. 13+23 is 33. The real numbers are 23.19 and 13.7, add them together and you get 36.89. The exact sum is 36.89 (:

What are two different way of factoring -3x-9? Select all that apply
Ghella [55]

Options:

A. –3(x + 3)

B. 3(x + 3)

C. 3(–x – 3)

D. –3(x – 3)

Answer:

A and C

Step-by-step explanation:

Given

-3x - 9

Required

Factorize

The options are not given; So, I'll answer on a general term

-3x - 9

Express -9 as -3 * 3

-3x - 9 = -3x - 3 * 3

Then factorize 3 out of the expression as:

-3x - 9 = 3(-x - 3)

Another way is to factor -3 out of the expression as:

-3x - 9 = -3x - 3 * 3

-3x - 9 = -3(x + 3)
