Full solution

Q. Evaluate the expression for x=0.4x = -0.4.\newlineWrite your answer as a decimal or whole number.\newline7x=-7x = _____
  1. Identify expression: Identify the expression to be evaluated.\newlineWe are given the expression 7x–7x and we need to substitute xx with 0.4–0.4.
  2. Substitute xx: Substitute xx with 0.4–0.4 in the expression.\newlineThe expression becomes 7×(0.4)–7 \times (–0.4).
  3. Multiply result: Multiply 7-7 by 0.4-0.4.\newlineMultiplying a negative by a negative gives a positive result.\newline7×0.4=2.8-7 \times -0.4 = 2.8
