Is -2/3(12b - 6 + 9b - 18) equivalent to 2b(b + 8)? Show your work.
AURORKA [14]

Answer:

No, they are not equivalent

Step-by-step explanation:

\frac{-2}{3}(12b - 6 + 9b - 18) = \frac{-2}{3}(12b + 9b - 6 - 18)\\\\=\frac{-2}{3}(21b - 24)\\\\  = \frac{-2}{3}*21b -24*\frac{-2}{3}\\\\= -2*7b + 8*2\\\\= 2( -7b + 8)
