How do you simplify this using the distributive property

3. solve the given inequality and graph the solution on a number line.

Use the method of cylindrical shells to find the volume v generated by rotating the region bounded by the curves about the given axis. y = 7ex, y = 7e^-x, x = 1; about the y-axis

Find the area of the region that is inside r=3cos(theta) and outside r=2-cos(theta). sketch the curves.
