Answer:
-12t
Explanation:
So let's use order of operations: PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction).
We see we have multiple pairs of parentheses, so we need to work inside out. Starting with (2 + (-4t)), this is simply equal to (2 - 4t).
Now, we have the 3 on the outside, so we distribute the 3:
3(2 - 4t) = 3 * 2 + 3 * (-4t) = 6 - 12t
Finally, we add -6 to this:
-6 + (6 - 12t) = 0 - 12t = -12t
Thus, the answer is -12t.
Hope this helps!
