A C D
Step-by-step explanation:
Sandy - 64 dozens = 768 single cookies.
Alejandro - 62 dozens = 744 single cookies.
Pierre - 60 dozens = 720 single cookies.
Pierre brought 720 cookies. You solve this by understanding that one dozen = 12 and multiplying 12 by the given number of dozens each student brought to find out the exact amount of single cookies. Hope this helped !
1. D; -5m+2m, because -5+2=-3
2. B; 4 terms, every part of an expression that's not the subtraction/addition sign counts as a term.

I hope this was helpful.
