The polynomial 2x^5-3^4+12x^3-2 is of degree​ . The leading coefficient is​ .

The polynomial 2x^5-3^4+12x^3-2 is of degree​ ___5. The leading coefficient is​ ___2.

Step-by-step explanation:

The degree of a term of a polynomial is the sum of the exponents of all the variables of the term. Remember that a variable such as x has exponent 1 (that we don't write), but it still counts.

The degree of a polynomial is the same as the degree of the term with highest degree.

The leading coefficient is the coefficient of the term with the highest degree.

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
