A rectangular prism has a length of 13ft and a width of 16ft. If the prism has a volume of 936ft3, calculate the height of
the prism. Make sure your answer includes the proper units.

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".

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
