Q. Which of the following are true statements about the expression 7+7-7+7 ?\newlineChoose 22 answers:\newline(A) The expression describes the number that is 77 to the left of 7-7 on the number line.\newline(B) The expression describes the number that is 77 to the right of 7-7 on the number line.\newline(C) The expression equals 14-14 .\newline(D) The expression equals 00 .
  1. Identify Result: Identify the result of the expression 7+7-7 + 7.\newlineCalculation: 7+7=0-7 + 7 = 0
  2. Evaluate Statement A: Evaluate statement A: The expression describes the number that is 77 to the left of 7-7 on the number line.\newlineIf we move 77 units to the left of 7-7 on the number line, we would be at 14-14, not 00.\newlineTherefore, statement A is false.
  3. Evaluate Statement B: Evaluate statement B: The expression describes the number that is 77 to the right of 7-7 on the number line.\newlineIf we move 77 units to the right of 7-7 on the number line, we would be at 00, which is the result of the expression 7+7-7 + 7.\newlineTherefore, statement B is true.
  4. Evaluate Statement C: Evaluate statement C: The expression equals 14-14. The calculation already showed that 7+7=0-7 + 7 = 0, not 14-14. Therefore, statement C is false.
  5. Evaluate Statement D: Evaluate statement D: The expression equals 00. The calculation already showed that 7+7=0-7 + 7 = 0. Therefore, statement D is true.
