Suppose CDEF represents the wing you built as part of the reconstruction of a vintage airplane model. CF is to be attached to the plane with CD closest to the propeller. You friend will build the second wing, QRST, congruent to CDEF, but needs instructions for how to place their wing exactly like you did. What are your instructions? a. Attach QR to the plane with SR closest to the propeller
b. Attach QR to the plane with QT closest to the propeller
c. Attach ST to the plane with QT closest to the propeller
d. Attach ST to the plane with SR closest to the propeller.

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".
