Bonita is testing prototype model rocket engines. to be considered a successful launch, the rocket must reach a height of at least 24 ft and must go a horizontal distance of no more than 10 ft. the vertical height must be at least three times as high as the horizontal distance. no rocket should go higher than 33 ft. the graph shows the feasible region, where x represents the horizontal distance and y represents the vertical distance. which ordered pairs meet all the constraints for a successful launch and make sense in context of the situation? select each correct answer.

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".
