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:
Answer:
The Answer is D
Step-by-step explanation:

Area of the figure = 27 square units
Solution:
Number of full squares shaded = 24
Number of half squares shaded = 0
Number of more than half square shaded = 3
Number of less than half square shaded = 4
Area of the figure = Number of full square + Number of more than half square
+ Half of number of half squares
= 24 + 3
= 27 square units.
Area of the figure = 27 square units
To solve this problem, we must use the formula:
Where:
• A = final amount = ?,
,• P = starting amount = $400.00,
,• r = interest rate in decimals = 4% = 0.04,
,• n = number of times per year that the interest is compounded = 1 (because interest is compounded annually),
,• t = time in years = 2.
Replacing the data of the problem in the equation above, we get:
