Q:
Find x so the distance between (x,4) and (4,2) is √5. (Enter your answers from smallest to largest value.
------------------------------------------------------------
A:
Using distance formula:
sqrt%28%28x-4%29%5E2+%2B+%284-2%29%5E2%29+=+sqrt%285%29, square both sides
%28x+-+4%29%5E2+%2B+4+=+5
%28x+-+4%29%5E2+=+1
x - 4 = 1 or x - 4 = -1
Therefore, x = 3, 5
