Joe wants to build a fence for his dog Charlie.
The lengths of the perimeter of the rectangle that he plans to surround with fence are as follows:
10 feet + 15 feet + 10 feet + 15 +feet.
The total perimeter area of a rectangle is worked out as follows:
10 + 15 + 10 + 15 = 50
Therefore Joe needs 50 feet of fencing to totally surround the rectangle with fence.
Factor the equation:

set each part of the factorized equation to zero and solve for x the results are your zeros:
x+3 = 0
x = -3x-8 = 0
x = 8
: -x/2+3/2<5/2=x>-2
-x/2+3/2-3/2= -x/2<5/2-3/2=1
-x/2<1
-x/2/2= -x<1/2
-x can be transformed into -1/2x
-1/2x / -1/2=x
1/-1/2=-2
<span>x>-2 </span>

It would be zero because you can’t raise 0 to any positive power.
