Answer:

C 1

Step-by-step explanation:

x-1/x-2 - x^2+4x-4/(x-2)(x+6)

rewrite: (x-1)(x+6)-(x^2 + 4x - 4)/(x-2)(x+6)

expand x^2+6x-x-6-x^2-4x+4/(x-2)(x+6)

collect like terms (x^2-x^2)+(6x-x-4x)+(-6+4)/(x-2)(x+6)

simplify x-2/(x-2)(x+6)

cancel x-2 and get 1/x+6

but that is the only answer I can get from this, so I believe many one, just because of the numerator

To solve this conversion factor problem we are going to multiply our original quantity 800hm by conversion factors (expressed as fractions) in order to cancel units until we get centimeters:
We know that 1 hectometer= 100 meters, so our first conversion factor expressed as a fraction is $\frac{100m}{1hm}$
We also now that 1 meter = 100 centimeters, so our second one is $\frac{100cm}{1m}$

Now that we have our fractions, lets multiply our original quantity by them to get our answer in the required units:
$800hm( \frac{100m}{1hm} )( \frac{100cm}{1m})=8000000cm$

We can conclude that 800hm are 8,000,000cm
