If the unknown number is x then decreasing it by 6 means subtracting 6 from it , so the expression is
x - 6
The equation of a circle with center (h,k) and radius r is

convert it to that form by comleting the square for the x and y terms
or, we can just expand what we know
expand

and make it equal to 0
so expanding we get

minus m^2 from both sides

arranging in decreasing power order with m² at the end

that is option A
answer is A

x = 81 large cats
</span>
How many small dogs are equal to 12 large cats?
x small dogs / 12 large cats = 6 small dogs / 9 large cats
