Answer:
x³=27
cuberoot√x³=cuberoot of 27
x=3
Each angle is 90 degrees because 90 times 3 is 270.
That's definitely an example of exponential decay, since the base (1/2) (also called the "common ratio") is greater than 0 but less than 1.
In a square, all sides are equal and all angles are equal.
So, the length of the side is only the height.
Therefore height can be:
1)The root of the area of square
2)The perimeter divided by 4
Answer:
Equation:
or 
Solution:
Step-by-step explanation:
The formula that is used to calculate the perimeter of a square is:

Where "s" is the side lenght the square.
Knowing that Xin used 20 yards of fencing to build the walls of a square chicken coop (in which the lenght in yards of each wall is represented with "x"), you can identify that:

Then, you can susbtitute values into the formula
:
Finally, you must solve for "x" in order to find its value.
This is:
