Answer:
You have not added the options, therefore, I cannot provide an exact answer. However, I can help you with the concept.
In any fraction, the denominator cannot be equal to zero because this would make the fraction undefined.
Excluded values are the values that would make the denominator equal to zero.
We are given that the excluded values are 2 and 5, this means that the factors of the denominator are (x-2) and (x-5)
This means that the denominator is x² - 7x + 10
Pick the fraction which has this denominator.
Hope this helps :)
You should graph it to find out, but you will see that (2, 5) does not lie on the line that the other coordinates do.
So this is a special triangle. The 30-60-90 triangle rule states that if the short leg is y, then the hypotenuse is 2y and the long leg is y√3.
In this case, the short leg is 5√3 since that times √3 makes 15.
Now with the hypotenuse, just multiply 5√3 with 2, and your answer should be 10√3, or C.
