2 hoses were used to fill a swiming pool. Water is pumped through the 1st hose at arate of 22 L/min and through the 2nd hose at a rate of 18L/min. Write an algabraic expression for each situation

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".

may i see the picture? it would a lot, xox

answer: b)
