Answer 2

Answer:

The given expression is "not(not(x ≤ 13) or not(x ≥ 7))".

Explanation:

To understand the given expression, let's break it down step by step.

1. x ≤ 13: This part of the expression checks if x is less than or equal to 13. 2. not(x ≤ 13): This part negates the result of x being less than or equal to 13. 3. x ≥ 7: This part of the expression checks if x is greater than or equal to 7. 4. not(x ≥ 7): This part negates the result of x being greater than or equal to 7. 5. not(x ≤ 13) or not(x ≥ 7): This part combines the negated results using the logical OR operator. 6. not(not(x ≤ 13) or not(x ≥ 7)): Finally, this part negates the result of the combined expression.

Let's evaluate each part of the expression using the given conditions.

Evaluation:

- x ≤ 13: This condition is true for any value of x that is less than or equal to 13. - not(x ≤ 13): This condition is true when x is greater than 13. - x ≥ 7: This condition is true for any value of x that is greater than or equal to 7. - not(x ≥ 7): This condition is true when x is less than 7. - not(x ≤ 13) or not(x ≥ 7): This condition is true when x is less than 7 or greater than 13. - not(not(x ≤ 13) or not(x ≥ 7)): This condition is true when x is between 7 and 13, inclusive.

Therefore, the given expression "not(not(x ≤ 13) or not(x ≥ 7))" is equivalent to "x is between 7 and 13, inclusive".

Conclusion:

The given expression evaluates to "x is between 7 and 13, inclusive".
