HELP ME WILL GIVE BRAINLIEST Part A: Create an example of a 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 polynomials. Give an example. (5 points)

(a) solve h+2/6 = h-3/4(b) solve the following simultaneous equations. 2x = y + 66x - 2y = 13x = ? y = ?

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )

With number 11 ( show how you got the answer)
