Ok so the best way to solve this problem is to simplify it as small as possible so first with the given equation 6(x+7)+3x you need to use the distributive property on 6(x+7)

This should get you 6x + 42

Then you have to add everything with like terms (or everything with the variable x) So add together 6x + 3x and that should get you 9x

So now you are left with

9x + 42 which is C

Hope this helps :D

Answer:

C. 9x+42

Step-by-step explanation:

The equation is 6(x+7)+3x

First, you would start with the distributive property...

6(x+7)

6 times x =6x

6 times 7= 42

So the equation comes to..

6x+42+3x

Combine the like terms

6x+3x= 9x

9x+42

So C would be your answer
