Part A: Create a third-degree polynomial in standard form. How do you know it is in standard form? (5 points)

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

sorry i dont know my friend

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
