Question

Wich of the following expressions is equivalent to 3x+3x+5+5?​

Answer 1

6x + 10

Explanation:

Combine like terms:

3x + 3x = 6x, and

5+5 = 10

and so the final sum is 6x + 10

Answer 2

OPTION B:
`2(3x+5)`

Explanation:

To solve the exercise you can simplify the expression given in the problem, as following:

- Add the like terms:

`3x+3x+5+5\\6x+10`

- Find the greatest common factor (GCF) of 6 and 10:

`6=2*3\\10=2*5\\\\GCF=2`

- Factor ir out.

Then, you obtain the following equivalent expression:

`2(3x+5)`
