The suspension cables of the George Washington Bridge approximate the shape of a parabola. The two support towers are 900 meters apart, and they reach 100 meters above
the roadway. If the cable reaches a minimum height of 10 meters above the roadway
between the two towers, determine the height of the cable 50 meters from either of the
support towers. Round answer to the nearest 1 decimal place.

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".
