### Problem 9 (assuming the first one is 9, maybe a typo)
# Explanation:
## Step1: Combine constant terms
$-4 + 3 = -1$
## Step2: Combine z terms
$7z - 2z = 5z$
## Step3: Combine results
$5z - 1$ (Note: The original handwritten answer $5z - 7$ is incorrect. Correct is $5z - 1$)

# Answer: $5z - 1$

### Problem 8
# Explanation:
## Step1: Combine constant terms
$17 - 3 = 14$
## Step2: Combine d terms
$2d - 2d + 4d = 4d$
## Step3: Combine results
$4d + 14$ (Note: The original handwritten answer $4d - 20$ is incorrect. Correct is $4d + 14$)

# Answer: $4d + 14$

### Problem 10
# Explanation:
## Step1: Combine k terms inside parentheses
$2k + 3k = 5k$
## Step2: Distribute 8
$8(5k + 1) = 40k + 8$ (Note: The original handwritten answer $5k + 8$ is incorrect. Correct is $40k + 8$)

# Answer: $40k + 8$

### Problem 12
# Explanation:
## Step1: Combine constant terms
$-4 - 5 = -9$
## Step2: Combine p terms
$8p - 6p + 20p = 22p$
## Step3: Combine results
$22p - 9$

# Answer: $22p - 9$
