Let's factorise and use the difference of two squares (D.O.T.S):
![\frac{5(x-2)}{(x+2)(x-2)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%28x-2%29%7D%7B%28x%2B2%29%28x-2%29%7D%20)
the (x-2) in the numerator and denominator cancel out so we are left with:
![\frac{5}{x+2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7Bx%2B2%7D%20)
So the answer is B
Answer:
yes it would as it is a survey that is completely at random, however you shouldn't say "oh, 682 in 1000 people in the united states use corrective lenses", because it could vary based on the location and other factors. hope this helps! :)
Step-by-step explanation:
Given that,
The polyhedron has 8 faces and 8 vertices.
From Euler's formula,
No. of edges, E=F+V−2
Substituting the values,
⇒E=8+8−2
⇒E=14
I think the answer is A.CMIIW
