Question 335686
 The length of a rectangular computer monitor is 6 inches less than twice its width. The perimeter of the face of the monitor is 36 inches. Find the length and width of the monitor. 
-----------
Draw the picture and label the 
width = x
length = 2w-6
---------------------
Equation:
Perimeter = 2(length + width)
36 = 2(2w-6+w)
18 = 3w-6
24= 3w
w = 8 inches (width)
length = 2x-6 = 2*8-6 = 10 inches
