It is more than one I think because it becomes -1 over -12 WITHOUT the -power and then add the power and it becomes positive. Make the power positive and it will become negative making it less than 1.
55+85=140
180-140=40
10x=40
divide by ten on each side
x=4
Answer:
See below
Step-by-step explanation:
L = length
W = 2 feet less than L = L-2
Area = L x W
20 = L * (L-2)
20 = L^2 - 2L
0 = L^2 - 2L - 20
Use Quadratic Formula a = 1 b = -2 c = -20
L = [-b ± sqrt(b^2-4ac) ]/2a
to calculate <u> L = 5.5826 ft then W = L-2 = 3.5826 ft </u>
