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:
67%
Step-by-step explanation:
Given : A department store buys 300 shirts at a cost of $1800 .
Then By unitary method , the cost of one shirt = Cost of 300 shirts divided by 300
= $1800 ÷ 300 = $6
i.e. cost of one shirt = $6
Also, Selling price of one shirt = $10
Price mark up = Selling price - Cost price
= $10-$6 = $4
The percent mark up=
(rounded to the nearest percent)
Hence, the percent markup = 67%
Answer:
Step-by-step explanation:

Example:
f(x) = 3x + 1
f(-x) = -1(3x) + 1
f(-x) = -3x + 1
