How would the fraction 5/1-√3
be rewritten if its denominator is rationalized
using difference of squares?

A.

Step-by-step explanation:

Please wait for more explanation:

The differences of squares:  a² - b² = (a - b)(a + b)

at denominator we have:  a - b  and we want:  a² - b²

so we need to multiply by (a+b)  {both denominator and nominator!}

The answer is  A

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
