meters fence

Step-by-step explanation:

Ben needs to replace two sides of his fence.

The length of one side of fence =   meters

The length of other side of fence = meters

to calculate the length of fence that Ben need to buy we will add the length of both sides.

+

= +

=

=

= meters

Ben need to buy   meters fence.

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".
