Imagine you have a rectangle and the base is the longer side. The base is x+2, the height is x-1, and the area is 54 ft^2. Find x and then find what the length and width are.

Area=length * width 54 = (x+2) (x-1) 54 = x^2-x+2x-2 0=x^2+x

There are 10 people on a basketball team and only 5 starters. How many different starting lineups can the coach have?

nCr=n!/(r!(n-r)!) n=10 r=5 10!/(5!(10-5)!)=252 There are 252 different starting lineups that the coach can have

If you 10 bulls all weighing about have a 2,300 pounds and you need to give them all penicillin how many bottles will you need and how much will it cost you? (1mL=100lbs) (1 bottle=100mL) (1 bottle=$15)

2300lbs/100lbs=23mL 23mL*10 bulls=230mL 230mL/100mL bottle=2.3 bottles (3 bottles) 3 bottles*$15=$45 You will need 3 bottles in order to have enough medicine for the 10 bulls and that will cost you $45.
