1. 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.
“Distribute” each term (very carefully).

7. The figure shows a proposed
sand pit, an area in a park that
will be filled with sand.
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?
