Problema Solution
The width of a rectangle is 5 inches less than 2 times the length. If x represents the length, write an algebraic expression in terms of x that represents the area of the rectangle. Simplify the expression.
Answer provided by our tutors
Let the width be w, and the length be x.
The first sentence gives us:
w = 2x - 5
The area of the rectangle is length times width.
x * w = x * (2x-5)
Therefore the Area, or A,
A = 2x2 - 5x
