Answer:
4 ft by 12 ft
Step-by-step explanation:
x^2 +8x -48
Set this equal to 0 to solve for the values of x
x^2 +8x -48=0
What two values multiply to -48 and add to 8
12*-4 = -48
12+-4 = 8
(x+12) (x-4) = 0
Using the zero product property
x+12 = 0 x-4=0
x=-12 x=4
We cant have a negative length
x=4
The area is 48
48/4 = 12
The other dimension is 12
65/6= 10.83333333
Or, 10 5/6 as a mixed fraction.
65/6 is also an improper fraction that represents 10.833333.
I hope this helps!

The x values stay the same but the y values change to their opposites.
For example: (2,4) reflected across the x-axis would be (2, -4)
and (6, -3) reflected across the x-axis would be (6, 3)
I hope you understand my explanation.
