Please help with this equation. I will give brainless for the first answer. Thanks!

5 =x

Step-by-step explanation:

The expression is undefined when the denominator goes to zero

25 - x^2 =0

Add x^2 to each side

25 = x^2

Take the square root of each side

sqrt(25) = sqrt(x^2)

±5 = x

We want the non negative value

5 =x

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%
