16. Use the distributive property to simplify the expression 4(8+ 2i). A: 12 + 2i
B: 32 + 8i
C: 12 + 8i
D: 40i

17. Use the distributive property to simplify the expression 4i(5 – 7i)

A: 28 - 20i
B: 28 + 20i
C: 9i – 28i2
9i– 3i2

Problem 16

4(8+2i)

4*8 + 4*2i

Problem 17

4i(5-7i)

4i*5 + 4i*(-7i)

20i - 28i^2

20i - 28(-1) recall that i^2 = -1

20i + 28

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%
