Q. Simplify to create an equivalent expression.\newline2(5n+6)+5(27n)-2(-5n+6)+5(2-7n)\newlineChoose 11 answer:\newline(A) 2-2\newline(B) 25n+10-25n+10\newline(C) 25n+2-25n+2\newline(D) 25n2-25n-2
  1. Distribute 2-2 across terms: Distribute the 2-2 across the terms inside the first parentheses.\newlineCalculation: 2×5n=10n-2 \times -5n = 10n and 2×6=12-2 \times 6 = -12.\newlineSo, 2(5n+6)-2(-5n+6) becomes 10n1210n - 12.
  2. Distribute 55 across terms: Distribute the 55 across the terms inside the second parentheses.\newlineCalculation: 5×2=105 \times 2 = 10 and 5×7n=35n5 \times -7n = -35n.\newlineSo, 5(27n)5(2-7n) becomes 1035n10 - 35n.
  3. Combine Step 11 and Step 22: Combine the results from Step 11 and Step 22.\newlineCalculation: (10n12)+(1035n)(10n - 12) + (10 - 35n).
  4. Combine like terms: Combine like terms.\newlineCalculation: 10n35n=25n10n - 35n = -25n and 12+10=2-12 + 10 = -2.\newlineSo, the expression simplifies to 25n2-25n - 2.
