I hope choice must be given so that we can select which equation can be used to find its value.
I am showing the steps for this problem.
Given that, x represents the width of the rectangle and the perimeter of the rectangle is 28 inches.
Let's assume y represent the length of the rectangle.
Formula to find the perimeter of a rectangle is,
p= 2 * length + 2 * width.
Hence, we can set up an equation as following.
2 y + 2x = 28.
Hope this is your question, if not I think you will, still be able to
find an answer of your question based on this solution.
Hope this helps you!.
Answer:
In the very first step, when they multiply both sides by 3 the -2y should become -6y but instead it stays as -2y. The correct solution would be:
9x - 6y =6
9x - 6y = 6
0 = 0
This means there are infinite solutions.
Option D is the correct answer
Further explanation:
Let
The perimeter of a rectangle is given by:
It is also given that:
So we can write as
We also know that The length of the rectangle is three times its width
Putting the value of l in the inequality
Rearranging the terms
Hence, option D is the correct answer.
