Q. Simplify the expression:\newline3(1+7x)=3(1 + 7x) = _____
  1. Expand and Multiply: Write 3(1+7x)3(1 + 7x) in expanded form.\newlineEach term inside the parentheses should be multiplied by 33.\newline3(1+7x)=3×1+3×7x3(1 + 7x) = 3 \times 1 + 3 \times 7x
  2. Simplify Expression: Multiply to write the simplified expression.\newline3×1+3×7x=3+21x3 \times 1 + 3 \times 7x = 3 + 21x\newlineTherefore, the simplified form of 3(1+7x)3(1 + 7x) is 3+21x3 + 21x.
