Question

Minnie has a piece of cardboard with length (3x2 − 2x + 1) inches and width (2x2 + 3x − 4) inches. Which statement best explains why the area of the cardboard demonstrates the closure property

Answer 1

It is equal to (6x4 + 9x3 − 12x2 + 8x − 4) square inches, which is also a polynomial like the length and width.
It is equal to (6x4 + 5x3 − 16x2 + 11x − 4) square inches, which is also a polynomial like the length and width.
The length multiplied by the width is equal to the width multiplied by the length.
The length multiplied by the width has the same degree as the width multiplied by the length
