How do I answer this
f(x) = x  3 (x + 4)^(1/2)
and am asked how to solve for x when y = 5
I have no idea how to do this and know that I could just solve it by guess and checking but I want to know how to do this algebraically when plugging in the 5 and trying to solve for x like so
5 = x  3 (x + 4)^(1/2)
and I don't know how to do that
also why is 22/7 pi???? is it just by luck??? kind of random but just have to know
