You can put this solution on YOUR website! The lenght of a rectangle is 2u+3 the width is 4u-18. The perimeter is 114 feet. What is the value of u?
Solution:
Use the fact that the perimeter of a rectangle is equal to
2L + 2W = P
2(2u+3) + 2(4u-18) = 114
(4u + 6) + (8u - 36) = 114
12u - 30 = 114
12u = 144
u = 144/12
u =
