Question

Anyone help with these questions?

Answer 1

So in this case expand the brackets where everything outside the brackets are multiplied into the brackets if that makes sense. Therefore 5 times 3m plus 5 time 2.

(5×3m)+(5×2)
=15m+10
do not add them together since they are not like terms

Do the same for the next question
which I think is already done for you since there is no expanding or adding to do.

Hope I am right if not sorry.
