THIS IS WORTH 10 POINTS BECAUSE OF IMPROPER ANWSERS FOR POINTS The following is an incorrect flowchart proving that point L, lying on line LM which is a perpendicular bisector of segment JK , is equidistant from points J and K:

What is the error in this flowchart?

A. JL and KL are equal in length, according to the definition of a midpoint.

B. An arrow is missing between ∠LNK = 90° and ∠LNJ = 90° and ∠LNK ≅ ∠LNJ.

C. An arrow is missing between the given statement and ∠LNK ≅ ∠LNJ.

D. Triangles JNL and KNL are congruent by the Angle-Angle Side (AAS) Postulate.

b

Step-by-step explanation:

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".
