Answer:
Your answers are 6m-2m+12 and 4(m+3).
Explanation:
This is because for 6m-2m+12, you are dealing with like terms. You are subtracting 6m-2m.
4(m+3) on the other hand, you are using the distributive property. You would carry the 4 to the m and to the 3.
Once you've done that with both of those expressions, they will both equal 4m+12.
