Kent can paint a certain house by himself in x days. His helper Keith can paint the same house by himself in x + 3 days. Suppose that they work together onthe job for 2 days. To complete the table on the next page, use the fact that the work completed is the product of the rate and the time. Write a rational expression for the fraction of the house that they complete by working together for 2 days. Evaluate the expression for x= 6.
