I have a couple of math questions that i cant seem to get to work out. can someone help me please.?
1.)
(x/x+6)-(6/x-6)=(x^2+36)/(x^2-36)

2.)
(r-2)-(2-r)=0

(8/ty^2)+(9/t^2y)

(7/w)+(8/w^2)

((r+10)/r)+(r/(r+10))

6.) divide
((z^2-1)/16z+16) / ((z-1)/4)

7.) find LCM
11(t-7) and 77(t-7)

8.) remove factors of 1
w^2-9 / 3-w

9.) divide and simplify
((d+2)/(d-4))/((8d+16)/(d-5))

I know that there are alot of questions but these are the one's that for some reason i just cant get to work out.
