Question 1109273
I need help. Can't solve it.

3.25(48x+x(x/6)+2x*sqrt((x/2)^2+(x/6)^2))=50000
-----------
It's just a matter of being careful.

13(48x+x(x/6)+2x*sqrt((x/2)^2+(x/6)^2)) = 200000
48x+x(x/6)+2x*sqrt((x/2)^2+(x/6)^2) = 200000/13
48x + x^2/6 + 2x*sqrt((x^2/4 + (x^2/36)) = 200000/13
48x + x^2/6 + 2x*sqrt((10x^2/36)) = 200000/13
48x + x^2/6 + 2x*(x/6)sqrt(10) = 200000/13
48x + x^2/6 + (x^2/3)sqrt(10) = 200000/13
x^2/6 + (2x^2/6)sqrt(10) + 48x = 200000/13
x^2*(2sqrt(10)+1)/6 + 48x - 200000/13 = 0
