Multiplication Algorithm Advanced FOIL Multiplying Polynomials: You can multiply polynomials vertically, just like you would in an ordinary arithmetic problem. The same pattern works with polynomials. *Fill in the “connectors” by showing whether the term is positive or negative. 1. 2. 3. “Distribute” each term (very carefully). 4. 5.

The sand pit is to be a large rectangular area twice as long as it is wide, plus a smaller rectangular area 3 feet long and as wide as the large area. The two areas share a common side. a. Write an expression for the total perimeter of the sand pit as a function of x. b. Write an expression for the total area of the sand pit as a function of x. c. The sand in the pit is to be 3 inches deep throughout. The park has 40 cubic feet of sand available. What will be the approximate dimensions of the sand pit? d. The pit is to be bordered by a chain link fence. How much fencing is needed?
