Solution:

Jamie buys 5 books for 7$. So draw array multiplication table using 5 rows and 7 columns (see the figure attached below)

By counting the number of rows and number of objects in each row from the figure attached below, we get the total cost of the book.

Total cost = number of rows total number of objects in each row

Total cost = 5 7 = 35

hello i might . what do you need.

friend me

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
