Q. Add.\newline(6d+6)+(d+9)(6d + 6) + (d + 9)
  1. Identify expression: We have: (6d+6)+(d+9)(6d + 6) + (d + 9)\newlineIdentify the expression after distributing the addition sign inside the parentheses.\newline(6d+6)+(d+9)(6d + 6) + (d + 9)\newline= 6d+6+d+96d + 6 + d + 9
  2. Combine like terms: Combine like terms.\newline6d+6+d+96d + 6 + d + 9\newline= (6d+d)+(6+9)(6d + d) + (6 + 9)\newline= 7d+157d + 15
