Question

Jessie has a piece of cardboard with length (2x2 − 4x + 5) inche and width (3x2 + x − 6) inchesWhich statement best explains why the area of the cardboard prove the closure property?

a It is equal to (6x4 − 10x3 − x2 + 29x − 30) square inches which is also a polynomial like the length and width

b It is equal to (6x4 + 2x3 − 12x2 − 12x − 30) square inches which is also a polynomial like the length and width

c The length multiplied by the width is equal to the width multiplied by the length

d The length multiplied by the width has the same degree as the width multiplied by the length

Answer 1

@phi

Answer 2

closure property
is the way people say, if you multiply two polynomials, the answer will be a polynomial

choice c sounds more like "commutative law"... so I would not choose it.

Answer 3

i thought that i was going more towards A. but idk

Answer 4

@phi

Answer 5

Yes, the answer is either A or B, because they show the answer is a polynomial
We should multiply out the polynomials to decide if the answer is A or B

Answer 6

hmmm.. im thinking it's A.
