Full solution

Q. Evaluate the expression for s=3s = -3.\newlines+18=s + 18 = _____\_\_\_\_\_
  1. Substitute s=3s = -3: Substitute s=3s = -3 into the expression s+18s + 18. We replace ss with 3-3 in the expression. s+18s + 18 becomes 3+18-3 + 18.
  2. Evaluate 3+18-3 + 18: Evaluate 3+18-3 + 18. We add 3-3 to 1818. 3+18-3 + 18 equals 1515.
