Answer:
- 8x = - 32
Step-by-step explanation:
Given
1 + 2x + 1 = 10, that is
2 + 2x = 10 ( subtract 2 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Then
- 8x = - 8 × 4 = - 32
When you want to know the amount of fencing needed, you have to find the perimeter of the enclosed space. For the shape of a rectangle, the perimeter is the sum of its sides. Its sides consist of 2 equal lengths and 2 equal widths. Therefore:
A = 2L + 2W = 18(2) + 45(2) = 126 feet
It will need 126 feet of fencing.
