Q. Simplify to create an equivalent expression.\newline2(3y+6)3(4y)2(3y+6)-3(-4-y)\newlineChoose 11 answer:\newline(A) 9y9y\newline(B) 5y+245y+24\newline(C) 9y249y-24\newline(D) 9y+249y+24
  1. Distribute the terms: First, distribute the 22 into the terms inside the first parentheses (3y+6)(3y+6) and the 3-3 into the terms inside the second parentheses (4y)(-4-y).\newlineCalculation: \newline2×3y=6y2 \times 3y = 6y\newline2×6=122 \times 6 = 12\newline3×4=12-3 \times -4 = 12\newline3×y=3y-3 \times -y = 3y
  2. Combine the distribution results: Combine the results from the distribution to form a new expression.\newlineCalculation: \newline6y+12+12+3y6y + 12 + 12 + 3y
  3. Group like terms and combine constants: Group the like terms (6y+3y)(6y + 3y) and combine the constant terms (12+12)(12 + 12).\newlineCalculation: \newline(6y+3y)+(12+12)(6y + 3y) + (12 + 12)
  4. Add like terms and constants: Add the like terms and the constants.\newlineCalculation: \newline6y+3y=9y6y + 3y = 9y\newline12+12=2412 + 12 = 24
  5. Write simplified expression: Write the simplified expression by combining the results from the previous step.\newlineCalculation: \newline9y+249y + 24
