Aferris wheel is drawn on a coordinate plane so that the first car is located at the point (0,20). what are the coordinates of the first car after a rotation of 270degrees° counterclockwise about the origin?

(20,0)

Step-by-step explanation:

That would bring the first car to the point (20,0)

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".
