Review the Conjecture
4. Answer the following questions about the amount of water used by showers and
leaking faucets. (4 polnts: 2 points for each answer)
A. Time to review the accuracy of your conjecture and that of your classmate. Is
your classmate's conjecture true - that the amount of water wasted per day is
equivalent to the amount of water used by 1 shower? Is your conjecture about the
scale of water waste in 1 day (cup, gallon, or shower) in question 3 true?

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".

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
