A cubic shipping container had a volume of a3 cubic meters. The height was decreased by a whole number of meters and the width was increased by a whole number of meters so that the volume of the container now is a3+2a2-3a cubic meters. By how many meters were the height and width changed. Note: Appendix A gives the formula for
Problem 1 Use grouping to factor the following polynomial completely. x^3 + ax + 3a + 3x^2 Note: Factoring means to express a polynomial or a number as a product of its factors (in the case of polynomials, the factors are prime polynomials).
After a heavy snowfall, Brian can shovel the entire driveway in 30 minutes. If his younger brother Allen helps, the job takes only 20 minutes. If we let x represent the time for Allen to clear the entire driveway by himself, write an expression for the following: ? Rate of work (job/minute=1 driveway/minute) by Brian ? Rate of

Simplify the following expression: (see attachment) Hint: The first step is to make the radical a perfect cube (so that exponent equals index) so as to eliminate the radical from the denominator. Note: A radical expression of index n is in simplified form if it has: ? no perfect nth powers as factors of the radicand ?
