A set has closure under an operation if performance of that operation on members of the set always produces a member of the same set; in this case we also say that the set is closed under the operation.
A closure property is a certain rule that holds <u>if it is true for all elements of a set under the given operation</u> and a closure property does not hold <u>if there is at least one pair of elements that do not follow the closure property under the given operation.</u>
Therefore, Emma is correct, because you can find a counterexample (7:2=3.5) that gives you a non-integer answer.
Answer: correct option is B
Answer:
6 cm,12 cm,8 cm
Step-by-step explanation:
add the perimeter of the first triangle to get 65
then divide 65 by 26 to get 2.5
then divide all the side lengths by 2.5
15/2.5=6
20/2.5=8
30/2.5=12
Answer: maybe 50.9
Step-by-step explanation: we can use the pythagorean theorem A^+B^=C^
36 x36 = 1,296
1,296 + 1,296 = 2,592
square root of 2,592 = 50.911688245431421756860794071549 rounded to 50.9
so your answer maybe 50.9
