PLZ HELP I WILL MARK BRAILNLEIST!! 20. b) Find the side length of the square. [No label is required.] *
iogann1982 [59]

Answer:

The length of one side is 13 feet.

Step-by-step explanation:

To start, a square is 4 sides that are equal in length. This means that when you have a problem like this, you need to set the equations equal to each other like:

2x+5=6x-11

In order to solve a problem like this, with the same variables on different sides, start by subtracting the smaller variable from both sides. In this case, you would be subtracting 2x from both sides, which would leave us with:

5=4x-11

After that, you solve it like a normal one-step equation. Add 11 to both sides.

16=4x

Now, divide both sides by 4 and you will know how much x is worth.

4=x

Now that we know how much x is worth, we can plug that into either of the equations given to us. It doesn't matter which since they are equal to each other.

2(4)+5

That would give us 13.
