Evaluting Algebraic Expressions Evalute each expression if n = 6 1. 3n + 4 2. N÷ 2 - 1 3. 15 - n 4. n^2 - 5 5. (N - 2) × 9 6. 4n ÷ (3 + 1) 7. (18 - n ) × 2

1. 3n + 4
3(6) + 4
18 + 4
22

2. N/2 - 1
6/2 - 1
3 - 1
2

3. 15 - n
15 - 6
9

4. n² - 5
6² - 5
36 - 5
31

5. 9(N-2)
9(6-2)
9(4)
36

6. 4n / 3+1
4(6) / 4
24 / 4
6

7. 2(18-n)
2(18 - 6)
2(12)
