Answer:
x1 = 0.16203454
x2= 0.04843273+0.06766624j
x3= 0.04843273-0.06766624j
Step-by-step explanation:
The better way to obtain roots of a polynomial when is not easy to analytically factorize is to use software as Matlab or Python. Use the following code in Python
import numpy as np
pol=np.array([1,-0.2589, 0.02262,-0.001122])
roots=np.roots(pol)
print(roots)
Answer:

Step-by-step explanation:
See attachment for grid
From the attachment:
There are 10 cells on the horizontal axis and there are also 10 cells on the vertical axis.
This implies that, the measurement of each cell is:



The horizontal axis has 7 selected cells.
This measures

The vertical axis has 4 selected cells.
This measures

So, the selected area is:


or

2/3 x 12/1 = 24/3 if you simplify it it equals 8 cups
