Answer:
The equation that demonstrates the distributive property is B.
Step-by-step explanation:
When you find the distributive property it depends if the first number on the outside can be distributed to the the other numbers to then create another equation that both numbers inside the parenthesis are multiplied but the number on the outside.
3(2+8)=3×2+3×8

I also need help with this too so I'm just here to wait and see the answer
