Francis makes two square pans of cornbread. He cuts one pan into 13 more pieces than the other pan. How many equal-size squares of cornbread does he cut in each pan?

6 and 7

Step-by-step explanation:

The first thing to do is to have square numbers starting from 1 and multiply them. For example

1 x 1 = 1

2 x 2 = 4

3 x 3 = 9

4 × 4 = 16

5 × 5 = 25

6 × 6 = 36

7 × 7 = 49

8 × 8 = 64

Then, we look for the squares that when we subtract the smallest from the biggest we have 13.

From the analysis above, the numbers are 49 and 36 as 49-36 = 13.

Hence 6 and 7 are the numbers as the squares of 6 and 7 are 36 and 49 respectively

10

step-by-step explanation:

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".
