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
0
It is not permissible for the denominator to be zero, so the "nonpermissible replacement" for x is 0.
-14°
-9 - 5
-9 + (-5)
-14
C. 4x squared -36
I need help with this question too but less hope we get a answer
