Hi
Yes 15 kilometers is 1500000 cm
This is because in metric conversion, you multiply by ten each time you convert to the next unit.
Heres a useful way to remember
K ing (kilo)
H enry (hecto)
D oesn't (deca)
U sually (unit) <-metre, litre ect.
D rink ( deci)
C hocolate (centi)
M ilk (milli)
Using logarithms property of log(x)+log(y)=log(xy)
so here, you can sum the equation to;

so you can simply say that;

and by multiplying (x+6)*(x-6)

and as you know also that;

is same as

so you can simply state it as;

And you can check your work by substituting with 10 instead of x in the original function.
Hope this helps!
Read this sentence in the problem carefully.
"<span>The number of pages in each program is determined by the number of graduates."
That means that you can have any number of graduates, and you will figure out the number of pages in the program depending on the number of graduates.
g, the number of graduates, is the independent independent variable.
p, the number of pages, is the dependent variable.
