i was stuck on one question on my homework...it says the area of a rectangle with length is 3x+2 and width 2 is 178ft squared. What is the perimeter of the rectangle?


x = 29

Length:    3(29) + 2, or 87 + 2, or 89

Width:     2 (given)

Perimeter: 2(89) + 2(2), or 178 + 4, or  units

You can do the check!! 



If you need a complete and detailed solution, let me know!!
