Step-by-step explanation:

You multiply 9 ×3 and get 27

Then you multiply 27×4 and get 108

And then you check your work.

Since 9×4 is 36 you multiply 36×3 and get 108.

So the new area is 3 times the old area.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
