A rectangle has a height of 5 and a width of 4x^2 – 2x – 6.

The area of the rectangle is units.

Step-by-step explanation:

Step 1:

The area of a rectangle is obtained by multiplying the length with the width of the rectangle.

Considering this a whole rectangle, the length of the rectangle is 5 units and the width is the sum of , , and -6.

So the length of the rectangle = 5 units and

the width of the rectangle units.

The area of a rectangle = (length)(width).

Step 2:

By substituting the known values, we get

The area of the rectangle

So the area of the rectangle is units.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
