A shipping container will be used to transport several 130-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 27000
kilograms. Other shipments weighing 6400 kilograris have already been loaded into
the container. Which inequality can be used to determine x, the greatest number of
130-kilogram crates that can be loaded onto the shipping container?

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".
