What is the value of N in the equation below?

8 = N x 8

Sherry couldn’t remember the product of 8 x 7. She decided to break the array for 8 x 7 into two multiplication combinations that she knew. Which two expressions below could be used to find the product of 8 x 7?

• (4 x 4) + (4 x 3)

• (7 x 5) + (7 x 3)

• (8 + 5) x (8 + 2)

• (7 + 4) x (7 + 4)

(7 x 5) + (7 x 3)

I can split 8 into 5 + 3. Now, I have 2 smaller arrays.

One array is 7 rows and 5 columns.

The other array is 7 rows and 3 columns.
