Q. Which of the following are true statements about the expression 7−(−7)?Choose 2 answers:(A) The expression describes the number that is 7 to the left of 7 on the number line.(B) The expression describes the number that is 7 to the right of 7 on the number line.(C) The expression equals 0 .(D) The expression equals 14.
Evaluate Expression: We need to evaluate the expression 7−(−7) to understand its value on the number line.Calculation: 7−(−7)=7+7=14
Determine True Statements: Now that we know the value of the expression is 14, we can determine which statements are true.Statement A suggests that the expression is 7 to the left of 7 on the number line, which would be 0. This is incorrect because the expression equals 14, not 0.
Statement A Evaluation: Statement B suggests that the expression is 7 to the right of 7 on the number line. Since the expression equals 14, and 14 is 7 units to the right of 7 on the number line, this statement is true.
Statement B Evaluation: Statement C suggests that the expression equals 0. This is incorrect because the expression equals 14, not 0.
Statement C Evaluation: Statement D suggests that the expression equals 14. This is correct because the expression 7−(−7) indeed equals 14.
