Actually, this is false. 6 and 4 both have <em>12 </em>in common because 6*2=12 and 4*3 is 12. So the least common denominator is really 12.
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
<u>2x³ - 3x² - 18x - 8</u> = 2x² + 5x + 2
x - 4
The answer is the second choice or B. 0.14
