Answer:
120poles
Step-by-step explanation:
Given
Length of each poles of the paddock = 30
Since a square has 4 sides, the perimeter of the square shaped paddock is what we are to look for.
Perimeter of a square = 4L
L is the length of each side of the paddock
Perimeter = 4(30)
Perimeter of the square = 120
Hence he used 120poles for the paddock
2n + 20 = -2
20 + 2 = -2n
22 = -2n
22/2 = n
11 = n
Answer - The difference between two positive integers can be either positive, negative or zero. When the first positive integer is larger than the second positive integer in a subtraction problem, the difference will be positive.
Note: 0 is neither positive nor negative
