5(a+2)= how to do????
To distribute means "to share; to pass out to others". So, if you want to distribute, you have to share the number on the outside of the parentheses with EACH number on the inside. So, you must multiply.
5 times a as well as 5 times 2 5*a = 5a; 5*2=10 so, the final answer would be 5a + 10
distribute the 5
(5*a) + (5*2) = 5a + 10
