Answer:

220 ways

Step-by-step explanation:

The order matters because there's going to be a first, second, and third place.

So, 12P3=12!/(12-3)!*3!=12!/9!*3!=12*11*10*9!/9!*3!=12*11*10/6=220

Therefore, 220 ways

If g (x) = 3x²-4, then find g (-3)

Semenov [28]

Answer:

g(-3) = 23

Step-by-step explanation:

This question is telling us that x = -3. Knowing this, we can plug x into the equation and solve to find g(-3).

$g(-3) = 3(-3)^{2} -4$

$g(-3) =3(9)-4$ Square -3 to get 9

$g(-3) = 27-4$ Multiply 9 by 3 to get 27

$g(-3) = 23$ Subtract 4 from 27 to get 23

Thus, g(-3) is equal to 23.

I hope this helps! Good luck!
