r^2: r^2 -60r -900 =0
doesnt make sense really
we can try lol

Other answers:

(r-30)^2 = 900+900 r = 30 +- sqrt(1800)
sqrt(1800) = 30sqrt(2) right? r = 30(1 +- sqrt(2)) maybe
amistre64, he has posted the same question earlier and I got a different answer: http://openstudy.com/groups/mathematics#/groups/mathematics/updates/4de40fa04c0e8b0b62caacd8
different is good, cause i dont think mine is right .... i got doubts lol
r^2 +81 = r^2 +60r +900 0 = 60r +900-81 r = (900-81)/60
(13.65 * 13.65) + 81 = (13.65 * 13.65) + 60(13.65) +900 It does not satisfy the equation
forgot a - sign lol
267.3225 = 267.3225
r = -13.65
would 12 be the answer ?
no 12 would not be the answer
you have too many equal signs can you rewrite the problem please
-13.65 is what i get
i get there is no solution
r^2 means r squared ...
