Answer:

The student incorrectly used the Distributive property!

Step-by-step explanation:

The Distributive property says a(b+c)=ab+ac

In this problem the answer SHOULD be 3n-15, however the <u>student forgot to distribute the 3 to the -5</u>!

Answer: The student did not distribute correctly

Step-by-step explanation: The student did not distribute correctly. The student has 3n correct because he multiplied 3 by n but -5 is not correct. He was supposed to distribute the 3 to the -5 to get -15.
