Express the product of 2x^2 + 6x - 8 and x + 3 in standard form

2x^3 + 12x^2 + 10x - 24

Step-by-step explanation:

Product means multiply

So

(2x^2 + 6x - 8) (x + 3)

= (2x^2 * x) + (2x^2 * 3) + (6x * x) + (6x * 3) - (8 * x) - (8 * 3)

= 2x^3 + 6x^2 + 6x^2 + 18x - 8x - 24

= 2x^3 + 12x^2 + 10x - 24

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.
