which expression represents "3 more than twice a number"?
3−2n3−2n
2n−32n−3
2n+32n+3
2+n+3

Hey there! Hello!

So, for this problem, I don't really see an answer choice that fits along with this description?? The last one is the closest to the answer I believe it is, but still doesn't fit exactly:

Twice a number = 2n
Three more than = +3
Final equation = 2n+3

Perhaps you have a typo either in your question or your answer problem, or I'm just way too tired. Either way, I hope this helped you out, and feel free to ask me any additional questions you may have.
