Q. Evaluate the expression for g=−4g = -4.\newline−5g=-5g = _____
  1. Identify expression: Identify the expression to evaluate.\newlineWe need to evaluate the expression –5g–5g with the given value of gg, which is –4–4.
  2. Substitute value: Substitute the value of gg into the expression.\newlineSubstitute –4–4 for gg in –5g–5g.\newlineExpression: –5×(–4)–5 \times (–4)
  3. Evaluate expression: Evaluate the expression.\newlineMultiplying a negative by a negative gives a positive result.\newline−5×(−4)=20-5 \times (-4) = 20
