Which of the expressions have like terms? Select all that apply A. -6m + 4m
B. t + 6.75t
C. 10m + mn
D. 6 - 6p
E. 9xy - 4xy
F. 2y + 5x

A, B, and E

Step-by-step explanation:

When talking about like terms you need to look at the variable. You have to look at which has the same variables and then you can determine which are like terms.

For A --> -6m + 4m both have m as a variable. They can be combined. Which is why they are like terms. Do the same for the rest.

What would NOT be like terms?

C-- 10m + mn

This is wrong because of the variable. the variable for 10m is m. When there is only a variable you can pretend there is a 1 (For example, m can be 1m but we ignore that). mn is a variable as a whole. So if we added one to the front, the variables of 10m and 1mn would not match! It does not matter if they both have an m, because the value would be different either way.

Hope this helps!!
