find u'(t)

Myininaya helped me with a similar problem, but I'm getting the wrong answer for this one for some reason.

Answer 1

I'm getting 1/[2(t-6)^(1/2)]

Answer 2

i am getting...

Answer 3

its supposed to be 36... my bad!

Answer 4

u(t)=sqrt(t^2-36) / sqrt(t-6)

Answer 5

ha makes a difference

Answer 6

answer is then 1/ (t+6)

Answer 7

Please show how you got that. It is correct though!
