What is the remainder when (3x4 + 2x3 − x2 + 2x − 19) ÷ (x + 2)? (1 point) Select one: a. 0 b. 5 c. 10 d. 15

B

Step-by-step explanation:

Given a polynomial divided by a factor (x + h) then the remainder is f(- h)

Given

f(x) = 3 + 2x³ - x² + 2x - 19 divided by (x + 2)

To find remainder evaluate f(- 2)

f(- 2) = 3 + 2(- 2)³ - (- 2)² + 2(- 2) - 19

        = 3(16) + 2(- 8) - 4 - 4 - 19

        = 48 - 16 - 4 - 4 - 19

        = 5 → B

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true

answer: 486in^2
