Be sure to SHOW YOUR WORK!!! Tests submitted with no work will be given a ZERO!!! 1.) You are one of five people who have been hired to mow the lawn at the local college. Each week, the dimensions of the plot you are responsible to mow changes. The college conducts a lottery, and whichever number is drawn, represents the x value. Your plot has a length which is three more than seven times x and the width is four times x minus 2.

a.) What are the dimensions of your mowing plot? Length: ______________________________________ Width: ______________________________________

b.) What is the area of your plot (remember area = length x width)? Area: _________________________________________

c.) If x = 10 meters, how many square meters is your plot? (show steps)Area: _________________________________________

2.) Factor by grouping: xy− 4y + 7x − 28

To frame a square piece of artwork such as a photo or print, a framing store bases it charge on the perimeter P, in inches, of the frame needed to surround both the artwork and a border around the artwork called a mat. A particular style of frame costs $1.50 per inch, while the glass costs $0.10 per square inch and the mat costs $0.15 per square inch. There is also a flat labor charge of $30. The total charge C for the framing is given by the function C(P) =1.5P+0.25(P4)2+30. In this function, what does the expression 0.25(P4)2represent?
