Answer: C. 2x - 10 = 4
Step-by-step explanation
2(x-5) is the same as 2x-10 because we multiply the outer 2 by each term inside the parenthesis.
- 2 times x = 2x
- 2 times -5 = -10
The general rule for the distributive property is: a(b+c) = ab+ac
Here's another example 7(x-3) = 7x-7*3 = 7x-21
Extra info: The distributive property is useful for multiplying large numbers on scratch paper.
