Which of the following best classifies a quadrilateral with coordinates a(7,0) b(3,1) c(4,7) and d(8,6)

Parallelogram

Step-by-step explanation:

I have plotted the given coordinates in a graph, so that you can see clearly what shape it is. However, in the exam you will not able to do that. Therefore, you would have to draw a sketch of the y- and x- axis, and then lable the coordinates quickly. Some practice on this would give you that skill.

Hope this helps. ☺

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".
