2xy for the first part?

sum of x&y= x+y.

Answer 11

thats the first part?

Answer 12

no, sum of x&y= x+y.

Get it?

Answer 20

i don't know what they expect you to write but don't you see that 2(x+y) & 2x+y are completely different?

Answer 21

ya

Answer 22

let's clear up the second one, shall we?
how you should answer these questions: as you read "the sum of", you ask yourself "ok, the sum of what?"
then, you read further & go "oh twice x is nothing but 2x" & you write 2x down.
You go on & read "and y" & you think "ok the sum of 2x & y -- that is 2x+y. So the answer is 2x+y."

Answer 23

would (2x+y) mean the same thing?

Answer 24

yes :)

Answer 25
