What’s the answer to 2(x+6) + 3x +4

First you would use the distributive property to multiply each term in the parentheses by 2. You should get something like this:
2x + 12 + 3x + 4
Next, combine all like terms (terms with x, and terms without x).
5x + 16
That is the final answer, because it cannot be simplified any further. Hope this helps!
