Use the distributive property to simplify the expression below: -4(3d - 1) + 4d I got this answer, 16d+4 is that correct ?

OpenStudy (anonymous):

-4*3d = -12d. -12d+4d=-8d So no.

OpenStudy (anonymous):

The -4*-1 being equal to 4 is correct though.

OpenStudy (anonymous):

Expand it as: -4(3d) - (-4)(1) + 4d Then simplify as: -12d + 4 + 4d -8d + 4
