Simplify quantity x squared plus 5 x plus 6 end quantity over quantity x plus 2

a. x2 + 1
b. x2 − 1
c. x + 3
d. x − 3

c

Step-by-step explanation:

Given

Factor the numerator

x² + 5x + 6 = (x + 2)(x + 3) , thus

=

Cancel the factor (x + 2) on the numerator and denominator, leaving

= x+ 3 → c

C. x+3

Step-by-step explanation:

Simplifying

x²++5x+6/x+2

Firstly we need to factorize the numerator to have;

x²+5x+6

x²+3x+2x+6

(x²+3x)+(2x+6)

x(x+3)+2(x+3)

x+2(x+3)

The equation will now become;

(x+2)(x+3)/x+2

= x+2 will cancel out x+2 to have x+3 left which is the required function

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%
