The Perimeter of Triangle ABC would be 60.
You can solve this by setting up proportions.
To start set up a fraction with the f(x) on top and g(x) on bottom
(f/g)(x) = (4x - 4)/(x - 1) - This is the function that we are going to use
Plug in -4 for x
(f/g)(-4) = (4(-4) - 4)/(-4 - 1) = (-16 - 4)/(-5) = (-20)/(-5) = 4
So...
(f/g)(-4) = 4
0.45 = 45/100
45/100 = 9/20 (Simplified)
The 9/5 put into a decimal is 1.8 so 1.8 times 100 is 180
