Drag each equivalent expression to the box where it belongs. some expressions may not belong in either box. yes: -3(4x + 12) -4(3x -9) 4(2x - 6) -4(-2x - 6) 3(-4x +12) 2(4x - 12) -12x + 36 8x - 24 no:

Assuming your target boxes are (-12x +36) and (8x -24), here are the classifications of the expressions with parentheses.

-3(4x + 12) = -12x -36 (neither)

-4(3x -9) = -12x +36

4(2x - 6) = 8x -24

-4(-2x - 6) = 8x +24 (neither)

3(-4x +12) = -12x +36

2(4x - 12) = 8x -24

The distributive property applies:

... a(b+c) = ab +ac

Same signs multiply to give positive. Different signs multiply to give negative.
