There is no distributive property in this problem. Distributive property is only used when it looks like this 5(7+1). You distribute the 5 to the 7 and the 1. But in that problem you can’t. You just add.
(distributive property comes when there is a number that need to be multiplied to the number inside the parenthesis. For instance, 2(x+4), in this you need to multiply 2 to all the no. inside the parenthesis)
