Stretch: Distribute and Combine Like Terms
I can use the distributive property and combine like terms to write equivalent expressions.
🧠 The Challenge
Two expressions are equivalent if they give the same value for every value of the variable.
You make equivalent expressions by distributing and combining like terms.
Example: 3(x + 2) = 3x + 6. And 3x + 6 + 2x = 5x + 6.
✏️ Your Turn
0 of 3 checks complete
1. Distribute: 4(x + 3) = ?
2. Combine like terms: 5x + 2 + 3x = ?
3. Which is equivalent to 2(n + 4) + n?
💬 Explain Your Thinking
Show that two expressions are equivalent by testing a value:
"blank equals blank. I checked with x = blank: both give blank."
