Question

Apply the distributive property to factor out the greatest common factor. 15+21=15+21=15, plus, 21, equals

Answer 1

15 + 21.....GCF = 3

3(5 + 7) <===

Answer 2

`3(5+7)`

Explanation:

We are asked to factor out the given expression using distributive property.

First of all, we will find greatest common factor of 15 and 21.

Factors of 15: 1, 3, 5, 15

Factors of 21: 1, 3, 7, 21.

We can see that greatest common factor of 15 and 21 is 3.

`15+21`

`3\cdot 5+3\cdot 7`

Factor out 3:

`3(5+7)`

Therefore, the factored form of our given expression would be
`3(5+7)`.
