Javon wanted to make a homemade exercise ball by pouring sand into a ball. he purchased 729 cubic inches of sand and wants to figure out the radius of the largest exercise ball that he could make. he will do this by solving the volume equation of a sphere for the radius. v = 4 3 πr3 after dividing the volume by π, javon is unsure of the next two steps to solve for r. complete the table to determine two possible next steps that he could do to each side of the equation to solve for r.

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".
