Answer:
4w + 9
Step-by-step explanation:
Area of rectangle = length x width (or base x height, depending on how you look at it).
It is given to you that:
Area = 8w + 18
Length = 2
Let: width = x
Plug in the corresponding terms with the corresponding words:
8w + 18 = 2x
Isolate the variable, x. Divide 2 from both sides of the equation:
(8w + 18)/2 = (2x)/2
x = (8w + 18)/2
w = (8w)/2 + (18)/2
w = 4w + 9
4w + 9 is the expression that represents the width of the rectangle.

A. 4+ 13w and C. 2(2+6w) + w
Hope this helps! They equal the same answer which is 13w + 4

$56
100 - (100(0.30)) = 100 - 30 = 70
70 - (70(0.20)) = 70 - 14 = 56
