Peaches are being sold for $2 per pound. If x represents the number of pounds of peaches bought and y represents the
total cost of the peaches, which best describes the values of x and y?
The values of both x and y can be any real number
The values of both x and y will be real numbers greater than or equal to 0.
The value of x can be any real number, but the value of y will always be a real number greater than or equal to 0.
The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or
equal to 0.

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".
