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:
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:
After that, you solve it like a normal one-step equation. Add 11 to both sides.
Now, divide both sides by 4 and you will know how much 
is worth.
Now that we know how much 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.
That would give us 13.

Hello,
<span>to find the percent of a number what we have to do is to multiply the number by de percent that we want to know and divide by 100, so:

Answer: 118% of 19 is 22.42
Solve the system by the elimination method.
2a + 3b = 6
5a + 2b - 4 = 0
multiply thru the top equation by 2
Multiply thru the bottom equation by 3
4a + 6b = 12
15a+ 6b = 12
Subtract and solve for "a":
11a = 0
a = 0
Solve for "b" using 2a + 3b = 6
2*0 + 3b = 6
b = 2
Answer:
the height of the building is approximately 134 yards
Step-by-step explanation:
Recall that i order to use the arc-length formula:
we know the radius R, but the angle 
must be given in radians. Then we convert 
to radians, and then use 1700 yards as the radius in the formula.
Therefore, the arc length formula would render:
which rounded to the nearest yard becomes: 134 yards
