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
3√(-50) = 3√(-1*50)=3i√(25*2) = 3*5i√2=15i√2
Answer:
the m angle ABC is 19x+12
They are not equivalent.
24/6= 4,
4/2=2
6/24= 0.25,
0.25/2= 0.125
2 does not equal 0.125
Final answer: Not equivalent
