\dfrac{x^4-2x^3+x^2+3x-2}{x^2-2x+1}

The degree of the numerator exceeds the degree of the denominator, so first you have to divide:

x^2+\dfrac{3x-2}{x^2-2x+1}

Now, x^2-2x+1=(x-1)^2, so the remainder term can be expanded to get

\boxed{x^2+\dfrac a{x-1}+\dfrac b{(x-1)^2}}

Equating the formula  (d is the diameter)

\pi d^2/4 = 132.7
d^2 = 132.7*4/\pi
d = \sqrt{169.044586}
d = 13.0017147331

56 is 80 percent of what number
monitta
Let us assume the number to be = x
Then
(80/100) * x = 56
4x/5 = 56
4x = 56 * 5
4x = 280
x = 280/4
  = 70
The value of the unknown number is 70. I hope the procedure is clear enough for you to understand. You can always use this method for solving similar problems in future without requiring any help from outside. Only thing that needs to be taken care of is the calculation part.
