Best ResponseYou've already chosen the best response.1@ outkast i think y = sqrt(52/11) u wrote y^2 = sqrt(52/13) ?

Best ResponseYou've already chosen the best response.1hey sorry , i took 4x^2 + 7y^2 but it is 4x^2 + 9y^2 , therefore the 4 solutions are : dw:1337656820684:dw

Best ResponseYou've already chosen the best response.2i believe you made a 9 really badly and thought it was a 7 the first equation is 4x^2+9y^2=72
