Explanation:
Hello.
Please keep in mind that the Distributive Property is really useful when it comes to simplifying expressions like the given expression.
Also remember that it states that:
a(b+c)=ab+ac
Basically, we take a number a and multiply it times b and c (b and c can be anything - numbers or variables)
Now, simplify:
7(2x+3y)
14x+21y
I hope it helps.
Have a great day.
