I need step by step instructions to figure out Can you help me figure out

would _R xe^xy dA be <, >, = 0, where R is the rectangle [1, 2] [3, 0]. Can you please explain how to figure this out so I can understand it?

would _D xy² dA be <. >, = 0, where D is the region x² + y² 16. Can you pelase explain how to figure this out?

- also can you explain step by step how to sketch to region of intergration in the xy plane and change the order of integration for

^{3 16-y^2} f(x,y)dx dy
