Answer:

  • A. (7 - √14x) /(7 - 2x)

Step-by-step explanation:

Given the fraction:

  • 7 / (7 + √14x)

Rationalize the denominator by multiplying (7 - √14x):

  • 7 / (7 + √14x) =
  • 7(7 - √14x) / (7 + √14x)(7 - √14x) =
  • 7(7 - √14x) /(49 - 14x) =
  • 7(7 - √14x) /7(7 - 2x) =
  • (7 - √14x) /(7 - 2x)
