Answer 1

Do you know what like terms are at all?

Answer 2

ya.... but i still need help with it i have like 5 questions i need to do this is the first one

Answer 3

It's D because all of the numbers have "x" after them, which is their like term in this case. If all the numbers have the same variable, or no variables, after them, then they have like terms. Does that make sense?

Answer 4

ya it makes sense but this question u choose more that one answer :P

Answer 5

Sorry, then it would be B and D because B has "jk" at the end of all of them, and D has "x" at the end of all of them. My bad lol

Okay, did you type all of the answers/question correctly..?

Answer 14

yes

Answer 15

i copy n pasted it so i couldn't have typed it in wrong

Answer 16

Okay, I'm going to say C. 5ba because the order of the variables doesn't matter. When multiplying, the order doesn't matter, as long as the number, letters, and amount of the variables stay the same. Does that make sense?
