-8,1
(w-8) (w+1) is the answer
The correct answer is B. Hope this helps!
Explanation:
Convert each fraction into an improper function.
In order to do that, take the whole number and multiply it by the denominator.
Then, add the numerator to the product and put it over the denominator.

![\large \boxed{x = \sqrt{164}}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7Bx%20%3D%20%5Csqrt%7B164%7D%7D)
Step-by-step explanation:
We have a right triangle, so we can use Pythagoras' Theorem:
The square of the hypotenuse equals the sum of the squares of the other two sides.
![\begin{array}{rcl}x^{2}&=& 8^{2} + 10^{2}\\& = & 64 + 100\\x^{2} & = & 164\\\end{array}\\\large \boxed{\mathbf{ x = \sqrt{164}}}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Brcl%7Dx%5E%7B2%7D%26%3D%26%208%5E%7B2%7D%20%2B%2010%5E%7B2%7D%5C%5C%26%20%3D%20%26%2064%20%2B%20100%5C%5Cx%5E%7B2%7D%20%26%20%3D%20%26%20164%5C%5C%5Cend%7Barray%7D%5C%5C%5Clarge%20%5Cboxed%7B%5Cmathbf%7B%20x%20%3D%20%5Csqrt%7B164%7D%7D%7D)
<u>Answer:</u>
W (-1, 4) ---> W' (-4, -1)
X (-1, 2) ---> X' (-2, -1)
Y (2, 2) ---> Y' (-2, 2)
Z (2, 4) ---> Z' (-4, 2)
<u>Step-by-step explanation:</u>
We are given the graph with a rectangular figure WXYZ and we are to find the coordinates of its vertices W'X'Y'Z' after the transformation of 90° rotation.
We know that, the rule for 90° rotation of a point (x, y) gives (-y, x).
So,
W (-1, 4) ---> W' (-4, -1)
X (-1, 2) ---> X' (-2, -1)
Y (2, 2) ---> Y' (-2, 2)
Z (2, 4) ---> Z' (-4, 2)
