Norman bought 116 feet of fencing to put around his backyard. The backyard is a perfect square. Write an equation to find the dimensions of his backyard. Is the area big enough for a pool that is 900 feet x2 ? Let s be the length of Norman's backyard.

116=perimeter
Since the backyard is a perfect square, the two sides are the same. Equation to find dimensions:
2x=116
x=58
To find the area of the backyard multiply x to itself.
58•58=3364
Area of total backyard: 3364 ft^2
Area of pool equation:
900•2=A
A= 1800
The area of the pool is less than the are of the backyard so yes, the pool will fit.

-167, because if you solve -18-x=9, x will be equal to -27. When you put -27 in place of the x in -5+6x, you get -167. Have a nice day!
