Answer:
something perpendicular probably
For a property with such a long name, it's really a simple math law. The multiplicative identity property states that any time you multiply a number by 1, the result, or product, is that original number. To write out this property using variables, we can say that n * 1 = n.
So to find the total animals you have to add both the cats and dogs so 16 and the dogs is 7 so 16/7
36 because NQ is 18 and the tic mark means that each half is equal to each other, and 18+18=36 :D
