Answer:
First & Third options
Step-by-step explanation:

In 12 years she will be X+12
2 years ago she was X-2
Julie : 5.62
Micah : 5.62 x 5 = 28.1
Jermy : 5.62 + 6.72 = 12.34
G(4) = 3x^2 - 3x - 9
Since the g(4) would be g(x) if you didn't know the number. So, substitute all of the x's for 4.
g(4) = 3(4)^2 - 3(4) - 9
g(4) = 3(16) - 12 - 9
g(4) = 48 - 3
g(4) = 45
I hope this helps you!
