Answer:
Sample Response: The student is not correct. He should use parentheses like this 9(n+13). Without the parentheses, it means nine times n plus 13, but should be the sum of n plus 13 multiplied by 9.
Step-by-step explanation:
No, the student is not correct.
The student used 9 times a number.
The sum of a number and 13 is n + 13.
The student should use parentheses.
The correct expression is 9(n + 13).
whichever to your preference ;)
