A square and a rectangle have the same perimeters. The length of a side of the square is 4x – 1. The length of the rectangle is 2x + 1 and the width is x + 2. Write and solve an equation to find x.

x = 1

Step-by-step explanation:

Since a square has four sides the perimeter of the square is =

Then, the perimeter of the rectangle will be =

By collecting like terms, we'll have:

Therefore, to find the value of x, we will equate both perimeters:

Collect like terms:

Now, divide both sides by 10:

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
