Bill is riding on a Ferris wheel with radius of
27 ft that is turning
counterclockwise at a rate
of one revolution every 15
seconds. Assume the lowest
point of the Ferris wheel (6
o'clock) is 8 ft above the
ground, and that Bill is at
the point marked A(3 o'clock)
at time t=0. Find his
position after 10 seconds
into the ride.

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".
