The final simplified answer is 6a + 5.
4(x - 3) = -12
4(x) - 4(3) = -12
4x - 12 = 12
+ 12 + 12
4x = 24
4 4
x = 6
One equation is 41t+63c=312

The answer is ten if I'm correct
Answer:
Its c
Step-by-step explanation:
The relevant rules of exponents are
.. (t^a)^b = t^(a·b)
.. t^a·t^b = t^(a+b)
You have
.. (t^-4)^-9·t^2
.. = t^((-4)*(-9) +2)
.. = t^38 . . . . . . . . . . . selection C
