Let's evaluate each expression by substituting \( X = 4 \):
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 would get a result of **10**.
- Parker would get a result of **83**.
- Nellie would get a result of **-20**.
Among these values, Parker's expression produces the largest value, which is **83**.
