How do the height and base length of the two triangles compare to the height and base length of the original piece of paper?
The two dimensions are the same in the triangles as they were in the rectangle.
The two heights are the same in the triangles as they were in the rectangle, but the bases of the triangles are half the
length of the base of the rectangle.
The two bases of the triangles have the same length as the base of the rectangle, but the triangles have heights equal to
half the height of the rectangle.
The two dimensions of the triangles are each half what they were in the rectangle.

Answer : The two dimensions are the same in the triangles as they were in the rectangle.

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".

it’s supposed to be -4+45=41
