Best ResponseYou've already chosen the best response.0Jim has a piece of cardboard with length (4x2 − 2x + 1) inches and width (3x2 + 3x − 4) inches. Which statement best explains why the area of the cardboard demonstrates the closure property? A. The length multiplied by the width is equal to the width multiplied by the length. B. The length multiplied by the width has the same degree as the width multiplied by the length. c. It is equal to (12x4 + 6x3 − 19x2 + 11x − 4) square inches, which is also a polynomial like the length and width. D. It is equal to (12x4 + 12x3 − 16x2 − 8x − 4) square inches, which is also a polynomial like the length and width.

Best ResponseYou've already chosen the best response.1You'll need to distribute (4x2 − 2x + 1)*(3x2 + 3x − 4). Do you know how to ?

Best ResponseYou've already chosen the best response.0to do that multiplication, you need to do \(3\times 3=9\) products, then combine like terms too much work for me, i would cheat
