very quickly #5. The world's fastest roller coaster is at Six Flags Magic Mountain. At the start, riders are shot forward and then up
a tower. They then begin the backward descent. The cars reach speed of 160 km/h in 7 seconds during the descent.
From a point 100 metres from the foot of the tower, the angle of elevation to the top of the tower is 52º. Find the height of the tower, to the nearest metre.

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".
