Lesson 6.14The Distributive Property
Set B · Version ASecond form · supported practice
Learning target I can use the distributive property to expand and factor expressions.
Why This Matters You're selling concert bundles at the music studio. Each bundle includes a ticket ($15) and a snack ($5). If 3 people each buy a bundle, you can calculate the total as 3(15 + 5) OR as 3 × 15 + 3 × 5. Either way, the total is the same — $60! This is the distributive property.
RememberThe Distributive Property
The Distributive Property. Formula: a(b + c) = ab + ac | a(b − c) = ab − ac The distributive property means you can multiply a number by everything inside the parentheses, one piece at a time: a(b + c) = ab + ac.
- Expand: Multiply the outside factor by each term inside parentheses.
- Factor: Find the GCF of terms and pull it outside: ab + ac = a(b + c).
- Visual: Represent as the area of partitioned rectangles

1Write the letter of the matching item on each line.
Match each a(b + c) light cue to its ab + ac expanded form.
- 2(b + c)
- 6(x + 2)
- 3(m + 5)
- 5(p + 1)
- A2b + 2c
- B6x + 12
- C3m + 15
- D5p + 5

2Write the name of the correct group on each line.
Sort each light-cue expansion: was the factor distributed correctly to BOTH terms, or only to one?
- 2(x + 6) = 2x + 12
- 4(n + 3) = 4n + 3
- 5(y + 2) = 5y + 10
- 3(a + 7) = 3a + 7
- 6(m + 1) = 6m + 6

A music studio is ordering supplies for 8 practice rooms. Each room needs a music stand ($12) and a stool ($9). The total cost can be written as 8(12 + 9). A student wrote 8(12 + 9) = 8 × 12 + 9 = 105. What went wrong?
- AThey added instead of multiplying
- BThey used the wrong prices
- CThey forgot to multiply the 9 by 8 as well
