Finding bounds of triple integral

[Larrytsai]

Homework Statement

Evaluate the triple integral of the function (x+5y)dV Where E is bounded by a parabolic cylinder and the planes z=9x z=0 y=18x and y=3x^2


I just wanted to knw if my bounds are correct.
Here they are

for dz:
0 to 9x

dy:

18x to 3x^2

dx:

0 to 6

Your limits for y are backwards, but otherwise everything looks okay.
