Most of the modern train are based on broad gauge. The separation in broad gauge is about 5 ft and 6 inches and in the standard gauge the separation between the tracks is 4 ft and $8\frac{1}{2}$ inches. So for the modern train it is not possible to travel on the tracks whose separation is no more than 4.5 feet.

If f(x) = 3x2 + 2 and g(x) = x2 – 9, find (f – g)(x).

hoa [83]

Answer:

2x^2 +11

Step-by-step explanation:

f(x) = 3x^2 + 2 and g(x) = x^2 – 9

(f – g)(x) = 3x^2 + 2 -( x^2 – 9)

Distribute the minus sign

3x^2 + 2 - x^2 + 9

Combine like terms

2x^2 +11
