Answer:
6x - 18
Step-by-step explanation:
3 x 6 = 18, so thats how you get the 18 in the answer
3 x 2x = 6x, which is how you get the 6x

Answer:
6x - 18
Step-by-step explanation:
3(2x - 6) =
("... - 6" means that whatever we do with the 6, we have to remember that it's negative)
3(2x - 6) =
3 * 2x + 3 * (-6) =
6x + (-18) =
(if we add a negative number then it's the same as subtracting that number)
6x + (-18) = 6x - 18
