Question

Which of the following uses the distributive property correctly?

3(x+5)=3-x+5
3(x+5)=3-x-3-5
3(x+5)=3+3.5
3(x+5)=3-x+3.5

Answer 1

None of them, 3x + 15 is correct.

Explanation:

In order to apply the distributive properly correctively, we need to multiply everything in the parentheses. For an example, lets look at the given expression:

`3(x+5)`

We multiply everything in the parentheses by 3

`3x+15`

Looking at out choices, none of them uses the distributive property correctly.
