Answer 1

the awenser is (2,3) and equal 5

Answer 2

.... that isn't even.. sigh. Anyone else?

Answer 3

you have 5 different questions. All of them are the same kind. I think you must study how to solve for them, not just get the answers.

Answer 4

Then I think someone should try to explain one of them so that I may understand them better ._.

Answer 5

do you know distance formula?

Answer 6

this right
