For what value of x is the rational expression below undefined? x-4 / 4+x a. 0 b. -4 c. -1 d. 4

The answer is option b. -4

Step-by-step explanation:

Given:

the rational expression will be undefined at the zeros of the denominator

To find the zeros of the denominator

the denominator = 0

∴ 4 + x = 0

∴ x = -4

So, the rational expression will be undefined at x = -4

The answer is option b. -4

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%

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
