P1= (-1,-5), P2 = (6, -6)

and i also need help with this problem

x 8

____ - ____

x^2-64 64-x^2

- trig -
**drwls**, Thursday, September 9, 2010 at 7:46amFor the first problem,

Distance = sqrt[(y2-y1)^2 + (x2-x2)^2]

= sqrt[(-1)^2 + 7^2] = sqrt 50 = 7.071..

Your second problem did not print out in a way that makes sense. I assume you meant

x/(x^2-64) -8/(64-x^2)

= x/(x^2-64) + 8/(x^2-64)

= (x+8)/[(x+8)*(x-8)]

= 1/(x-8)
