-18(1) = -18,right?
4(3) = 12, right?
-18 - 12 = -30
From the looks of it, we had to "Subtract" the outcome of each problem that we went over
You're correct: -30 (option A.) would be your answer
Yes.
For example, the LCM of 12 and 36 is 36, because factoring these numbers gives
12 = 2^2 * 3
36 = 2^2 * 3^2
So, to match them, just multiply the twelve by 3, then they're both 36.
I think the answer would be 4 and the reason why is because
