Answer:
<h3> -5n = 1 ⇒
n = -¹/₅</h3><h3> n+15 = (-10) ⇒ n = 25</h3><h3> n/5 = -1/5 ⇒ n = -1</h3><h3> n-13= -12 ⇒ n = 1</h3>
Step-by-step explanation:
-5n = 1
÷(-5) ÷(-5)
n = -¹/₅
n + 15 = (-10)
-15 -15
n = -25
n/5 = -1/5
×5 ×5
n = -1
n - 13 = -12
+13 +13
n = 1

Step-by-step explanation:
Complete question
Jimmy is putting up a fence around his rectangular garden. One side of the garden is 20 feet long, and b represents the width, How much fencing material will he need.
To get the amount of fencing material needed, we will find the perimeter of the fence
perimeter of the fence = 2(L+W)
L is the length
W is the width
Given
Length = 20feet
Width = b feet
perimeter of the fence = 2(20+b)
perimeter of the fence = 2(20) + 2b
perimeter of the fence = 40+2b cm
Hence the amount of material needed will be (40+2b)cm
The answer is 56 square meters
