The expression that represents the area of the rectangle is 2x² + 6x − 20. Thus, the correct option is C.
<h3>What is a rectangle?</h3>A parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. A rectangle is always a parallelogram and a quadrilateral but reverse statement may or may not be true.
The area of the rectangle is the product of its length and its width. Therefore, the area of the given rectangle is,
Area = (2x-4)(x+5)
= 2x² + 10x - 4x - 20
= 2x² +6x - 20
Hence, the expression that represents the area of the rectangle is 2x² + 6x − 20. Thus, the correct option is C.
The complete question is:
Write a simplified polynomial expression in standard form to represent the area of the rectangle below.
- 2x² + 10x + 20
- 2x² + 6x + 20
- 2x² + 6x − 20
- 2x² − 4x − 20
The image of the rectangle is given below.

You may go the super easy way and choose 1 as the whole number and 0.28 as the decimal number. Then you'd obviously have
Otherwise, to be a bit more creative, you can observe that
And since 1/25=0.04, you can also choose 7 as the integer, and 0.04 as the decimal to get
