Q. y3(3y+5) -y-3(-3 y+5) \newlineWhich of the following is equivalent to the given expression?\newlineChoose 11 answer:\newline(A) 8y15 -8 y-15 \newline(B) 8y+5 8 y+5 \newline(C) 8y5 -8 y-5 \newline(D) 8y15 8 y-15
  1. Distribute the 3-3: Distribute the 3-3 inside the parentheses.y3(3y)3(5)amp;=y+9y15\begin{align*}-y - 3(-3y) - 3(5) &= -y + 9y - 15\end{align*}
  2. Combine like terms: Combine like terms.\newline(y+9y)15(-y + 9y) - 15\newline=8y15= 8y - 15
