Dentro de la finca desean colocar una piscina, de forma rectangular triple de larga que de ancha, con una superficie de 108 m2 (metros cuadrados) y una profundidad de 2m y medio.(Calcula primero las dimensiones, ancho y largo, de la piscina) ¿Cuántos litros de agua son necesarios para llenar la piscina?

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".

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?
