Which choice is equivalent to the fraction below when x is greater than or equal to 2?

D. 2(√{x} + √{x - 2})

Step-by-step explanation:

As hinted in the question, we have to simplify the denominator.

To understand it easier, let's imagine we have x - y in the denominator.  If we multiply it with x + y we'll get x² - y², right?  Check the next line:

(x - y) (x + y) = x² + xy -xy - y² = x² - y²

If we have the square of those nasty square roots, it will be much simpler to deal with.  So, let's multiply the initial fraction using x+y, but with the real values:

Then we simplify:

Answer is D. 2(√{x} + √{x - 2})

answer: t=3

step-by-step explanation:

the correct answer is x/3+10≥32

hope this !
