Answer 2

It seems like there might be a typo or missing information in your expression. It looks like you have two sets of coordinates (x + 2, 3) and (+7, 8), but there is an operator missing between them.

If you want to add the corresponding coordinates, the expression would be:

$(x + 2 + 7, 3 + 8)$

Simplifying this expression gives:

$(x + 9, 11)$

If you meant something else, please provide more details or clarify the expression.
