Q. Equations and Inequali\newlinekadenh137137@alpineschools.net Switch account\newline* Indicates required question\newlineQuestion 44\newline11 point\newline44. Which expression is equivalent to 9y12(4y+20) 9 y-\frac{1}{2}(4 y+20) ?\newlineF. 11y10 11 y-10 \newlineG. 7y10 7 y-10 \newlineH. 7y+10 7 y+10 \newlineJ. 11y+10 11 y+10
  1. Simplify Expression: Simplify the expression inside the parentheses: (4y+20)(4y + 20).
  2. Multiply by 11/22: Multiply the simplified expression by 12\frac{1}{2}: (12)(4y+20)=2y+10\left(\frac{1}{2}\right)(4y + 20) = 2y + 10.
  3. Subtract from 9y9y: Subtract the result from 9y9y: 9y(2y+10)=7y109y - (2y + 10) = 7y - 10.
