Answer:
integers are closed under division
Step-by-step explanation:
Integers are not closed under division.Let us consider two integers i and j.
Then ![\[\frac{i}{j}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7Bi%7D%7Bj%7D%5C%5D)
need not necessarily be an integer. For example, 2 and 3 are integers but ![\[\frac{2}{3}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B2%7D%7B3%7D%5C%5D)
is not an integer. So the first option , namely, integers are closed under division is not true.
On the other hand, the remaining three options given are correct.
Area=side^2
10-y is the side
(10-y)^2 is area
aera=100-20y-y²
For 5-3/12 the equivalent expression is 60/12-3/12 And then for 1-4/9 the equivalent expression 9/9-4/9
Answer: It would be 7. (0,7)
