Answer:

Piper's claim that 3(2a+2) is equal to 5a +6 is incorrect.

Step-by-step explanation:

The first step is to use the distributive property to distribute the 3 to BOTH the 2a and 2. The resulting expression is 6a+6 NOT 5a+6. Piper's mistake was most probably that she added 3 and 2 to get 5 instead of multiplying them together to get 6.
