Answer
The answer is 6x+9
Explanation:
Unlike the other bad response above, that does not provide explanantion, I will explain why this is the correct answer
1. Multiply each term in parenthesis by 3 to get
3 x 2x +3 x 3
2. Multipy 3 x 2x, to = 6x
You now get 6x +3 x 3
3. Now, add the 3's together to equal 6x + 9
