Part A: Create a fifth-degree polynomial with three terms in standard form. How do you know it is in standard form? (5 points) Part B: Explain the closure property as it relates to subtraction of polynomials. Give an example.

yep

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

51-50
