C

Step-by-step explanation:

Given

(x + 7)(x + 1)(x + 4) ← expand the second/ third factors using FOIL

= (x + 7)(x² + 5x + 4)

= x(x² + 5x + 4) + 7(x² + 5x + 4) ← distribute both parenthesis

= x³ + 5x² + 4x + 7x² + 35x + 28 ← collect like terms

= x³ + 12x² + 39x + 28 → C

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%
