Give an example of a polynomial f(x) with integer coefficients which factors (poly mod n), but which has no roots, i. e., for which there are no integers x such that f(x) ≡ 0 (mod n). remark: your solution should give a specific integer n, and give all of the coefficients of f(x). it should show that f(x) really does factor, and it should prove that f(x) has no roots.

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
