When adding/subtracting fractions you need a common denominator, but you already have one, which is x-3. So in general:
a/c-b/c=(a-b)/c so you just have:
(2x-6)/(x-3) now if you factor 2 from the numerator
2(x-3)/(x-3) the (x-3)s cancel out leaving
2
However! Note that division by zero is undefined, so x cannot equal 3. (because both original fractions had denominators of x-3)
What this all means is that that expression will equal 2 for all real values of x other than 3.

Answer: -2
Step-by-step explanation: The average rate of a function f(x) from x=a to x=b is given as:
Clearly we are asked to find the average rate of change from x=0 to x=2.
i.e. a=0 and b=2
Also, from the graph it could be observed that:
f(0)=1
and f(2)=-3
Hence, the average rate of change is calculated as:
Hence, the average rate of change for this quadratic function for the interval from x = 0 to x = 2 is:
-2
27 in3 is the answer. this is because all dimensions of a cube are the same and if it fits a sphere of diameter 3 than the dimensions are 3x3x3 therefore 3*3*3 is 27 in3
