The length of a rectangle is 3 inches greater than the width. write a polynomial that represents the area of the rectangle

Length of a rectangle is 3 inches greater than the width, so:

L = W + 3

Area of a rectangle:

A = L x W

A = ( W + 3 ) x W

A = W2 + 3 W Polynomial representing area of the rectangle in terms of Width.

Substitute W = 4 to find the area of the rectangle.

A = 42 + 3 (4)

A = 16 + 12

A = 28 inch2

L = W + 3

L = 4 + 3

L = 7 inches

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.

step-by-step explanation:

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
