Answer:
- x ≥ 0: x|x| = x²
- x < 0: x|x| = -x²
Step-by-step explanation:
<u>For x ≥ 0</u>
|x| = x
so
x|x| = x(x) = x²
<u>For x < 0</u>
|x| = -x
so
x|x| = x(-x) = -x²

Jack needs 72 feet of fencing.
You had to do 4 ft x 18 ft which would give you the answer of 72. To find the area of a rectangle you do length x width.
