2m^3 + 5 reason: you may take 3m^2 out of the two 6m^5 and 15m^2. it is then divided out via the backside of your fraction. what's left is 2m^3 (when you consider that 2m^3 * 3m^2 is 6m^5) + 5 (when you consider that 5 * 3m^2 is 15m^2).

-3(10x + 4y) + 6(6x - 2y)
= -3(10x) + (-3)(4y) + 6(6x) - 6(2y)
= -30x - 12y + 36x - 12y
= -30x + 36x - 12y - 12y
= 6x - 24y
(answer B)

First, you multiply.
-3(10x + 4y) + 6(6x -2y) =
-30x - 12y + 36x - 12y
Then you add/subtract.
6x - 24y
so the answer is B.
