Question

2. Rewrite by factoring the GCF from each expression.a) 8r + 12O 8 (r + 3)O 4 (2r + 3)O 4 (2r + 12)O 8 (r + 12)

Answer 1

We are asked to rewrite the given expression by factoring the GCF from the expression.

`8r+12`

GCF is the greatest common factor.

Factors of 8 = 1, 2, 4, 8

Factors of 12 = 1, 2, 3, 4, 6, 12

Notice that the greatest common factor is 4

So, take out 4 from the expression

`8r+12=4(2r+3)`

Therefore, the correct answer is

`4(2r+3)_{}`
