The length of the sides of a square measure 2x-5. The length of a rectangle measures 2x, and the width measures x + 2. For what value of x is the perimeter of the square the same as the perimeter of the rectangle?

Step-by-step explanation:

Perimeter of a square:

The perimeter of a square of side x is given by:

Perimeter of a rectangle:

The perimeter of a rectangle of length l and width w is given by:

The length of the sides of a square measure 2x-5.

This means that the perimeter of the square is:

The length of a rectangle measures 2x, and the width measures x + 2.

This means that the perimeter of the rectangle is:

For what value of x is the perimeter of the square the same as the perimeter of the rectangle?

This is x for which:

So

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
