Part A: Create a fifth-degree polynomial with four terms in standard form. How do you know it is in standard form? (5 poi

Part B: Explain the closure property as it relates to subtraction of polynomials. Give an example. (5 points)

Step-by-step explanation:

Part A

The degree if a polynomial is the highest power to which its variable is raised. A fifth degree polynomial is one in which the highest power to which its variable is raised is 5.

Example of such polynomial is

3x^5 + 4x^4 + 6x^3 + 4x^2 - 30

It is in standard form because the powers to to which the variable is raised is decreasing orderly.

Part B

The closure property of polynomials when subtracting leads to a possible change in the coefficients of the polynomial only. Example is

(5x² + 3x + 2) - (3x² + x + 1) = 5x² - 3x² + 3x - x + 2 -1 = 2x² + 2x + 1

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00
