Question

Rewrite the following expression 15+21 using the GCF and the distributive property

Answer 1

First, we want to find the GCF of 15 and 21, which is 3. Now we do 15 divided by 3 and 21 divided by 3, which gives us 5 and 7. To rewrite the expression, we take the GCF and put it on the outside of the parenthesis. Inside the parenthesis, we put 5 + 7. So it'll look like this:

3(5 + 7)

Answer 2

`3(5+7)`

Explanation:

We are asked to rewrite 15+21 using the GCF and the distributive property.

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

`15=3* 5` and
`21=3* 7`.

We can rewrite our given expression as:

`3* 5+3* 7`

Now, we will factor out 3 from our expression as:

`3(5+7)`

Therefore, after rewriting our given expression using the GCF and the distributive property we will get
`3(5+7)`.
