First, distrbute -3 to both -4y and 3
-3(-4y) = 12y -> note that two negatives multiplied = one positive answer
-3(3) = -9 -> note that one negative and one positive = one negative answer
12y - 9 + 7y -> combine like terms
12y + 7y - 9
19y - 9 -> answer
Your answer is 19y - 9
hope this helps

The thing that is true about -5 and 5 is the answer is zero.
Multiplying ,you get 18x^2+21x-24x-28. You simplify to get:
18x^2-3x-28.
The Answer is C, my good friend.
