Select the procedure that can be used to show the converse of the Pythagorean theorem using side lengths chosen from 6 cm, 8 cm, 9 cm, and
10 cm.

Step-by-step explanation:

Some sides are given to us and we need to show the converse of Pythagoras Theorem . So the statement of Converse of Pythagoras Theorem is ,

Converse of Pythagoras Theorem :-

If in a triangle the sum of squares of two sides is equal to the square of third side then the angle opposite to the longest side is 90° .

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".
