Isabelle is using a square piece of cardboard to make a box without a lid. she cuts 2-inch squares from each corner and folds up the edges. the finished box has a volume of 98 cubic inches. which equation can be used to find the dimensions of the original cardboard piece?

2(w-4)^2

Step-by-step explanation:

the equation, my explanation is i got it off of imagine math.

x = 23.78

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.
