Question

Evaluate the expression for q = –47, r = 40, and s = –14.

qs − r = Evaluate the expression for f = –369.

2f + (2f + 707)2 =
Your answer:

Answer 1

To evaluate both expressions, we will substitute the given values accordingly.

### First Expression: \( qs - r \)

Given:
- \( q = -47 \)
- \( s = -14 \)
- \( r = 40 \)

Now substituting the values:

1. Calculate \( qs \):
\[
qs = (-47) \times (-14) = 658
\]

2. Now substitute \( qs \) and \( r \):
\[
qs - r = 658 - 40 = 618
\]

### Final answer for the first expression:
\[
qs - r = 618
\]

### Second Expression: \( 2f + (2f + 707)^2 \)

Given:
- \( f = -369 \)

Now substituting the value of \( f \):

1. Calculate \( 2f \):
\[
2f = 2 \times (-369) = -738
\]

2. Now compute \( (2f + 707) \):
\[
2f + 707 = -738 + 707 = -31
\]

3. Now calculate \( (2f + 707)^2 \):
\[
(-31)^2 = 961
\]

4. Finally, substitute into the expression:
\[
2f + (2f + 707)^2 = -738 + 961 = 223
\]

### Final answer for the second expression:
\[
2f + (2f + 707)^2 = 223
\]

---

### Summary of Answers:
1. \( qs - r = 618 \)
2. \( 2f + (2f + 707)^2 = 223 \)
