Name three kinds of parallelograms to complete the hierarchy. quadrilaterals parallelograms

Rhombus

Rectangle

Square

Step-by-step explanation:

A parallelogram is a shape of four sides, quadrilateral, that has equal and opposite sides. In this case, the problem is asking to name three kinds of parallelograms to complete the hierarchy.

In the hierarchy, quadrilaterals come first because a quadrilateral is a polygon of four edges, no matter if the sides of the polygon are irregular.

Then comes the parallelograms that are quadrilaterals with equal, opposite sides.

And some types of parallelograms are:

Rhombus in which all the sides are equal but the angles are not right angles

Rectangle that has right angles

Square all the sides are equal and it has right angles

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".
