Question

30a + 39b what is the answer

Answer 1

`3(10a + 13b)`

Explanation:

1) Find the Greatest Common Factor (GCF).

GCF = 3

2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

`3( (30a)/(3) + (39b)/(3) )`

3) Simplify.

`3(10a + 13b)`

Therefor, the answer is 3 ( 10a + 13b)
