That depends on the numerical value of W.
Area = L x W. L = 3W - 8 so A = 3W2 - 8W or W(3W - 8)

l x w =8 (1) l - w = 2 (2) transpose (2) l = 2+w sub into (1) w(2+w)=8 w 2 +2w - 8 = 0 (w+4)(w-2) = 0 w= -4,2 width = 2 feet, length = 2+2 = 4 feet
-2
That depends on the numerical value of W.
15-w
Six less than w can be represented as: w-6
less than
-8 is less than 8
w - 18
Area = L x W. L = 3W - 8 so A = 3W2 - 8W or W(3W - 8)
-8 is less than all positive numbers, including 8. -8 is 8 less than 0, and 0 is eight less than 8.
-8 < 8 Think of a thermometer scale. -10 degrees is colder than (+)10 degrees
8 less than a number would be written as 8 - 5. or 8 - A No! 8 less than a number, say X, would be X - 8.

8 - 13 = -5.
