Kendall is making cupcakes for a party. She 1/8 uses of a 4-pound bag of sugar to make a batch of cupcakes. Each batch has 24 cupcakes.
Drag one expression next to each question. The correct expression for each row is a
way to answer that question.

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".

yes.. it's proven to be 36.

3xy cannot be combined with the others

2x, -5x and x are like terms
