Four polynomials are shown below: a. 4 − 7x5 + x2 b. 5x3 + 5 − 3x4 c. 3x + 2x4 − x2 + 6 d. 3x3 − 5 + 2x5 + x which of the above polynomials is a 4th degree trinomial? polynomial a polynomial b polynomial c polynomial d

Polynomial B

Step-by-step explanation:

We are given 4 different polynomial. We need to choose 4th degree polynomial from given.

Degree is maximum power of x of polynomial.

Option A:

Degree = 5,  False

Number of term = 3 (Trinomial)

Option B:

Degree = 4

Number of term = 3 (Trinomial)

True

Option C:

Degree = 4

Number of term = 4 (Not Trinomial)

False

Option D:

Degree = 5

Number of term = 3 (Trinomial)

False

Hence, Polynomial B is correct whose degree 4 and number of term 3.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

the answer is a.
