A rectangle has a height of 4 and a width of 2x^2-x

Perimeter:  

Area:  

Step-by-step explanation:

I will assume the question asks for perimeter and area of the rectangle with given dimensions.

The height is "4"

The width (assuming) is ""

First, the perimeter:

Perimeter is sum of all 4 sides of a rectangle, so we have 2 widths and 2 lengths, we sum them up:

Now, the area:

Area is the height times width, so it will be:

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
