Question

Three classmates are working with three different expressions. Each classmate substitutes in the value x = 4 into their expression.
Eleanor: 5x - 10
Parker: 5x^2 + 3
Nellie: 5^x - 40
When substituting in the value x = 4, what would each classmate get a result of?

Let's calculate the result for each classmate by substituting \( x = 4 \) into their respective expressions.

**Eleanor's expression**:
\[
5x - 10
\]
Substituting \( x = 4 \):
\[
5(4) - 10 = 20 - 10 = 10
\]

**Parker's expression**:
\[
5x^2 + 3
\]
Substituting \( x = 4 \):
\[
5(4^2) + 3 = 5(16) + 3 = 80 + 3 = 83
\]

**Nellie's expression**:
\[
5^x - 40
\]
Substituting \( x = 4 \):
\[
5^4 - 40 = 625 - 40 = 585
\]

Now, summarizing the results:
- Eleanor gets **10**.
- Parker gets **83**.
- Nellie gets **585**.

Thus, the final results are:
- Eleanor: 10
- Parker: 83
- Nellie: 585
