Question

Which expression is equivalent to 4(−3.7b − 3.1) − (4b + 0.4)?

A - 18.8b + 2.7
B - −18.8b − 2.7
C - 18.8b − 12.8
D - −18.8b − 12.8

Answer 1

D. i got this correct

Answer 2

4(-3.7b) = (-14.8b), 4(-3.1) = (-12.4)

(-14.8b - - 3.1) = (-14.8b + 3.1)

(-14.8b + 3.1) - (4b +0.4) = (-18.8b - 12.8)

Your answer is C and D. — (I’m assuming you meant to put a plus sign in either C or D so make sure you do the one with the negative sign for -12.8)
