Thanks so much if your respond!
I mostly need help on the name the property.

Respuesta :

B.
This is something called the distributive property. How do you do that?

Multiply the number outside the parenthesis in this case; .25. to the number within the parenthesis; the coefficient "2d" and "1".

Therefore, it's .50d+.25. Hope this helps!
