The model shows the expression 30 + 12.
Slav-nsk [51]

Answer:

4rth   6(5+2)

Step-by-step explanation:

This is because 6 rows of 5 squares means that there is 6 rows with 5 squares each. 6 × 5 = 30. Then there is another set of 6 rows with 2 squares in each, which is 6 × 2 = 12. 30 + 12 = 42. Which is why 6(5+2) = 42. 6(5+2) = 6(5) + 6(2) = 6(7) = 6 × 7 = 6 + 6 + 6 + 6 + 6 + 6 + 6 or 7 + 7 + 7 + 7 + 7 + 7 or 5 + 5 + 5 + 5 + 5 + 2 + 2 + 2 + 2 + 2 + 2 = 42.
