Milo must put 50 feet of fencing around his rectangular garden. The length of the garden is one foot longer than twice the width. Find the solution set for 2w + 2(2w + 1) = 50 given the replacement set {6, 7, 8, 9} to determine the width of the garden.

2(2w + 1) + 2w = 50

4w + 2 + 2w = 50

6w + 2 = 50

6w = 50 - 2

6w = 48

w = 48/6

w = 8

--------------------------------------... Cara drives for 4 hours at a rate of 45 miles per hour. Later, she drives for another 3 hours so that her total distance traveled for the day is 336 miles. Find the solution set for 4(45) + 3r = 336 given the replacement set {52, 53, 54, 55} to determine the rate at which Cara traveled during the second part of her trip.
