Really need understanding! very stuck on this question! abcd is a parallelogram. find the value of x and y. answers: a. x = 35; y = -4 b. x = 10; y = 19 c. x = 4; y = 2 d. x = 3; y = 4

Sketch the region enclosed by the given curves. decide whether to integrate with respect to x or y. draw a typical approximating rectangle and label its height and width. y= 5x, y=7x^2then find the area s of the region.
