Question

the length of a rectangle is 3 feet less than 4 times the width. if the perimeter is 84 feet, find the length and the width of the rectangle.

Answer 1

length: 33, width: 9

write it out as 4x-3(2) + 2x. simplify that and you gey 84= 10x-6. add the 6 over and you get x=9, this is your width. know you just do 4(9) - 3 to find length, which equals 33
