When this net is folded into a cube, which two letters appear on opposite sides

B and E

Step-by-step explanation:

We are given the net of a cube.

When we fold them, we get a cube.

When we fold the given net, the side A, side D, side C, and side F become the  four sided of the cube.

The side B will be the bottom and the side E will be the top.

Now let's list down the opposite sides.

i) A and C

ii) D and F

iii) B and E

From the given choices, we see the option B and E.

Therefore, the answer is B and E

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".

exactly you go it
