\frac{16}{21,3} = \frac{25}{?} → \frac{[21,3][25]}{16} → \frac{532,5}{16} = 33,28125 \\ \\ 33,3 ≈ P

Help! find g(x)-f(x) if f(x)=-3x+4 and g(c) =5x-12
Marianna [84]
Replace f(x) and g(x) with what they equal:

5x - 12 - (-3x + 4)
5x - 12 + 3x - 4

Combine like terms:

5x + 3x = 8x
-12 - 4 = -16

8x - 16

The answer is C.
