Question

Rewrite the following expression 9(6+7n)

Answer 1

Answer:

63n + 54

Step-by-step explanation:

9(6+7n)

First you have to multiply 6 and 9 which gives you 54. Then you’ll have to multiply 7n and 9 which equals to 63n. Whenever you see expressions like that, make sure to multiply both numbers inside the parentheses by what’s outside the parentheses. (Well, that method is mainly done like that if there’s one number outside the parentheses—like the expression you’ve provided.)
