Abaseball player swings and hits a pop fly straight up in air to the catcher. the height of the baseball in meters t seconds after it is hit is given by the quadratic function h(t)=-4.9t^(2)+34.3t+1. how long does it take for the baseball to reach its maximum height? what is the maximum height obtained by the baseball?

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".

angle addition postulate

2x=56
