Hello!
We can solve this problem using the Distributive Property, which states the following:
a(b + c) = ab + ac
a(b – c) = ab – ac
In this case, we’ll use the first of the two formulas. Insert any known values into the equation as follows:
a(b + c) = ab + ac
5(6x + 3y) = 5(6x) + 5(3y)
Now simplify the right side of the equation:
5(6x + 3y) = 30x + 15y
We have now proven the given expression to equal (30x + 15y).
Consequently, the correct answer is D.
I hope this helps!
