Question 720797
Find x so the distance between (x, 2)and (3, 3) is sgrt 5.

I know that you need to use the distance formula, however I do not know how to get rid of the x.
---------------
You don't get rid of it, you solve for it.
-----
Use the distance formula:
{{{diffy^2 + diffx^2 = 5}}}
{{{1^2 + (x-3)^2 = 5}}}
{{{(x-3)^2 = 4}}}
x-3 = 2 --> x = 5
------------
x-3 = -2 --> x = 1
