How does changing the dimensions affect the area of a rectangle

Even when the dimensions aren't being squared in an area formula, they might be multiplied together, so a change in one dimension can have a significant effect on the area. For example, the area for a rectangle may be calculated using A = LW, where the length L is multiplied by the width W.

the answer is 28

step-by-step explanation:

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.
