Can anyone give me some insight on this?

Disagree, because a polygon has to have sides to be a polygon. A circle has no defined sides to categorise it as such. A circle is a closed system, but can be seen as a cycle that lasts until the world ends. Like infinity, a circle is infinite by definition because it goes on forever. Like the polygon comparison, a circle is technically in a different category. Infinity is typically described as a time full of endless possibilities while a circle is just that, a cycle that will repeat itself over the course of forever.

So still disagree on that argument. Please tell me this is for a Philosophy class or something, because having this as a math problem is horrible.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

grab rope, tie a loop-de-loop, put it around ur neck, now jump while its tied to a high place. now your shoes are cool.
