if you multiply by t 2 both sides i came up w3ith t= 14/c answer was wrong. can u help?
Math problem: c= 6t + 8/t solve for t?
Multiply everything by t
c(t) = 6t(t) + (8/t)(t)
ct = 6t^2 + 8
Subtract ct from each side
0 = 6t^2 - ct + 8
Now use the quadratic formula.
Let a = 6, b = -c and c = 8
Reply:c= 6t + 8/t
Do it step by step. It will help.
c= 6t^2 + 8
-----------
t
ct= 6t^2 + 8
0= 6t^2 - ct + 8
Then just factorize.
Note: the reason why your answer is wrong, is because you are trying to make X the subject. They asked you to evaluate here, not just make X the subject.
