Let's substitute $ x = 4 $ into each of the classmates' expressions and calculate the results: 1. **Eleanor's Expression: $ 5x - 10 $** $$ 5(4) - 10 = 20 - 10 = 10 $$ 2. **Parker's Expression: $ 5x^2 + 3 $** $$ 5(4^2) + 3 = 5(16) + 3 = 80 + 3 = 83 $$ 3. **Nellie's Expression: $ 5x - 40 $** $$ 5(4) - 40 = 20 - 40 = -20 $$ Now, let's summarize the results: - Eleanor: $ 10 $ - Parker: $ 83 $ - Nellie: $ -20 $ From these calculations, Parker produced the largest value of $ 83 $. So, the final answer is: - Eleanor would get a result of **10**, - Parker would get a result of **83**, - Nellie would get a result of **-20**. The expression produced the largest value is Parker's: **$ 5x^2 + 3 $**.
