Solve the equation by completing the square. x^2+2x=17

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.

Solve -.016x= -16. need solving this
