To factor the expression
${\displaystyle 3x^3-4x^2+6-8}$
completely.

Luis and raul are riding there bicycles to the beach from their respective homes. Luis proposes that they leave their respective homes at the same time and plan to arrive at the beach at the same time. The diagram shows Luis position at two points during his ride to the beach. Write an equation in slope intercept form to represent Luis's Ride from his house to the beach. If raul lives 5 miles closer to the beach than Luis, At what speed must Raul ride for the plan to work?

Simplify. Assume that variable a is nonzero.
${\displaystyle c^2{a}^{-3}}$
${\displaystyle c^2{a}^{-3}}$=${\displaystyle B\otimes }$ (Use positive exponents only. Simplify your answer.)

A bicycle with tires of radius r=15 inches is being ridden by a boy at a constant speed - the tires are making five rotations per second. How many miles will he ride in minutes? (1mi = 5280 ft)

To simplify: The given expression.
${\displaystyle {\left(x^{14}\right)}^{23}}$
