Answer:

The correct answer is 30!

Hope this helps! Good luck! :D

Step-by-step explanation:

x + 2 = 5

That means x = 3

3(3 + 2) + 3(3 + 2)

3(5) + 3(5)

15 + 15 = 30

If x+2 equals 5 then it would be x+2-2=5-2, so x= 3

Then you would plug it in and it would be 3(3+2) + 3(3+2)

Simplify it to 3(5) + 3(5)

Then multiply and it would be 15 + 15= 30  

30 is your final answer.

Hope this helped!
