Absolute value always means it is the positive version of the number
This switches -7 to 7 and 5 stays the same.
5 + 7 = 12
We can solve the above question as
5b-4=2b+17
5b-2b=17+4 (taking like terms together)
3b=21
b=21/3
b=7
Hence the value of b is 7
Answer:
Step-by-step explanation:
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
She placed 56 feet of fencing around her garden. This means that the perimeter of the garden is 56 feet. If the length of the rectangular garden is 20 feet, i means that
2(20 + W) = 56
Dividing through by 2, it becomes
20 + W = 28
W = 28 - 20
W = 8 feet
The formula for determining the area of a rectangle is expressed as
Area = length × width
Therefore,
Area = 8 × 20 = 160 square feet
