2. Piper claims that \( 3 ( 2 a + 2 ) \) is equivalent to \( 5 a + 6 \) . She checks her claim by subsituting \( - 3 \) lor a. Is Piper's claim correct? Why or why not? 

(A) Yes. Piper correctly distributed the \( 3 \) to both terms and added the values together. 

(B) Yes. Both expressions equal \( - 9 \) when \( - 3 \) is substituted into the expression for a.

C) No. Piper should multiply the \( 3 \) to \( 2 a \) to get an answer of \( 6 a + 3 \) . 

(D) No. Piper should distribute the \( 3 \) to both terms and add the values to get \( 6 a + 6 .\)
