Best ResponseYou've already chosen the best response.0Your right the only options for X2 are 3 or 4, and since the distance formula starts with (x2 x1) then none of the above qualify!

Best ResponseYou've already chosen the best response.0There is a good lesson in this, you done everything right, and if at the end of the day, you have done things right and the answer still doesnt come out, then you have to have confidence in what you do.
