Autumn has a bathtub that cannot hold more than 80 gallons of water. The bathtub is currently holding 6 gallons of water. Autumn adds more water at a rate of 3 gallons per minute. Which of the following inequalities shows the number of minutes, m, that Autumn can add water to the bathtub? 3m + 80 < 6

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".
