The length of a tennis court is 10 feet shorter than 3 times its width x express and the perimeter of the tennis court in terms x

First, let's define our variables.

Let's call our width X(given)

and our length, since it's 10 shorter than 3 times the width, we can call our length:

3x-10

So, the perimeter of a rectange is equal to 2 times the length + 2 times the width.

So, when we plug our values in, we get

The perimeter is 8x-20
