The difference of the given fraction is expressed as $\frac{x^2+4x-1}{x(x+2)}$

Given the expression:

$\frac{x+5}{x+2}-\frac{x+1}{x^2+2x} \\$

Take the LCM of the fraction to have:

$=\frac{x+5}{x+2}-\frac{x+1}{x(x+2)} \\=\frac{x(x+5)-(x+1)}{x(x+2)} \\=\frac{x^2+5x-x-1}{x(x+2)}\\=\frac{x^2+4x-1}{x(x+2)}$

Hence the difference of the given fraction is expressed as $\frac{x^2+4x-1}{x(x+2)}$

Answer:

12 possible outcomes

Step-by-step explanation:

Choosing 1 vehicle from 2 = 2C1 = 2

Choosing 1 color from 3 = 3C1 = 3

Choosing 1 type from 2 = 2C1 = 2

Number of possible outcomes :

2C1 * 3C1 * 2C1

2 * 3 * 2

= 12 different possible outcomes
