Sure! Let’s solve each of the 10 problems step by step. The goal is to
simplify algebraic expressions by using the
distributive property and then
combining like terms where possible.

Problem 1: -3(9 + 6w) + 8
Step 1: Distribute -3 to both terms inside the parentheses:
-3 × 9 = -27
-3 × 6w = -18w
So we get:
→
-27 - 18w + 8
Step 2: Combine constant terms (-27 + 8):
→
-19 - 18w
✔ Final Answer:
-18w - 19
*(We usually write variables first, but either order is acceptable unless specified.)*

Problem 2: 4(-5y - 9)
Step 1: Distribute 4:
4 × -5y = -20y
4 × -9 = -36
✔ Final Answer:
-20y - 36
---
Problem 3: 9(-5 + 3c)
Step 1: Distribute 9:
9 × -5 = -45
9 × 3c = 27c
✔ Final Answer:
27c - 45

Problem 4: -3(6 - 5r)
Step 1: Distribute -3:
-3 × 6 = -18
-3 × -5r = +15r *(negative × negative = positive)*
✔ Final Answer:
15r - 18

Problem 5: 8(-9p - 2) + 7
Step 1: Distribute 8:
8 × -9p = -72p
8 × -2 = -16
Expression becomes:
→
-72p - 16 + 7
Step 2: Combine constants: -16 + 7 = -9
✔ Final Answer:
-72p - 9
---
Problem 6: 2(-4 + 8h)
Step 1: Distribute 2:
2 × -4 = -8
2 × 8h = 16h
✔ Final Answer:
16h - 8
---
Problem 7: -8(-3 + 6w) - 7w
Step 1: Distribute -8:
-8 × -3 = +24
-8 × 6w = -48w
Expression becomes:
→
24 - 48w - 7w
Step 2: Combine like terms (-48w - 7w = -55w)
✔ Final Answer:
-55w + 24 or
24 - 55w
---
Problem 8: 7(-9r - 5)
Step 1: Distribute 7:
7 × -9r = -63r
7 × -5 = -35
✔ Final Answer:
-63r - 35
---
Problem 9: -6s - 7(2 + 9s)
Step 1: Distribute -7:
-7 × 2 = -14
-7 × 9s = -63s
Expression becomes:
→
-6s - 14 - 63s
Step 2: Combine like terms (-6s - 63s = -69s)
✔ Final Answer:
-69s - 14
---
Problem 10: -6 + 4(-9y + 8)
Step 1: Distribute 4:
4 × -9y = -36y
4 × 8 = 32
Expression becomes:
→
-6 - 36y + 32
Step 2: Combine constants: -6 + 32 = 26
✔ Final Answer:
-36y + 26
