There are two problems that no matter what I attempt to do, can not acquire the right answer for on my current assignment , I hope that someone here can quickly help me figure them out.

The total area enclosed by the graphs of y=12x^2 – x^3 + x

y=x^2 + 31x

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Then find the area of the region.

2y+2x=5, y = 3, 2y = 3(x)^(1/2)
