how many equal sections divide a directed line segment if it is to be partitioned with a 9: 12 ratio?

Write the expression in complete factored form. 5n_(c - 3) - n(c - 3) =

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.

Estimate the area under the curve f(x) = 16 - x^2 from x = 0 to x = 3 by using three inscribed (under the curve) rectangles. answer to the nearest integer.
