Question

The length of a rectangle is 5(x+2) units. The width of the rectangle measures (2x-1) units. Set up and simplify an alegebraic expression to find the difference between the rectangles length and width.

Answer 1

(3x + 11) units

Explanation:

The length of a rectangle is 5(x+2) units.

The width of the rectangle measures (2x-1) units.

The difference between the rectangles length and width is given as:

Length - Width

(5(x + 2) - (2x - 1) units

(5x + 10 - 2x + 1) units

(5x - 2x + 10 + 1) units

(3x + 11) units

Therefore, the algebraic expression for the difference between the rectangles length and width is given as:

(3x + 9) units
