Full solution

Q. Multiply. Write your answer in simplest form.\newline3d+55d2d+43d+5\frac{3d + 5}{5d^2} \cdot \frac{d + 4}{3d + 5}
  1. Write Problem: Write down the problem to identify the expressions to be multiplied.\newlineWe have: (3d+5)/(5d2)×(d+4)/(3d+5)(3d + 5)/(5d^2) \times (d + 4)/(3d + 5)
  2. Multiply Expressions: Multiply the numerators together and the denominators together.\newlineExpression becomes: (3d+5)(d+4)(5d2)(3d+5)\frac{(3d + 5) \cdot (d + 4)}{(5d^2) \cdot (3d + 5)}
  3. Expand Numerators/Denominators: Expand the numerators and the denominators.\newlineNumerator: (3d+5)(d+4)=3d2+12d+5d+20=3d2+17d+20(3d + 5) * (d + 4) = 3d^2 + 12d + 5d + 20 = 3d^2 + 17d + 20\newlineDenominator: (5d2)(3d+5)=15d3+25d2(5d^2) * (3d + 5) = 15d^3 + 25d^2
  4. Write Expanded Expression: Write the expression with the expanded numerator and denominator.\newlineExpression becomes: (3d2+17d+20)/(15d3+25d2)(3d^2 + 17d + 20) / (15d^3 + 25d^2)
  5. Cancel Common Factors: Look for common factors in the numerator and the denominator that can be canceled out.\newlineThere are no common factors between the numerator and the denominator, so the expression is already in its simplest form.
  6. Write Final Answer: Write down the final answer.\newlineFinal answer: (3d2+17d+20)/(15d3+25d2)(3d^2 + 17d + 20) / (15d^3 + 25d^2)
