Q. Evaluate the expression for c=−7c = -7.\newline10−c=10 - c = _____
  1. Identify Expression: Identify the expression to evaluate.\newlineWe need to substitute c=−7c = -7 into the expression 10−c10 - c.
  2. Substitute Value: Substitute −7-7 for cc in the expression.\newlineExpression after substitution: 10−(−7)10 - (-7)
  3. Evaluate Expression: Evaluate the expression 10−(−7)10 - (-7).10−(−7)=10+710 - (-7) = 10 + 7 (because subtracting a negative is the same as adding the positive equivalent)10+7=1710 + 7 = 17
