Q. Evaluate the expression for m=−3m = -3.\newline−4m−18=-4m - 18 = _____
  1. Substitute m=−3m = -3: Substitute m=−3m = -3 into the expression −4m−18-4m - 18.\newline−4(−3)−18-4(-3) - 18
  2. Evaluate multiplication: Evaluate the multiplication −4-4 times −3-3.−4(−3)=12-4(-3) = 12
  3. Add to −18-18: Now, add the result of the multiplication to −18-18.12−1812 - 18
  4. Calculate final result: Calculate the final result.\newline12−18=−612 - 18 = -6
