The length of a rectangle is 4 units greater than its width, and the area of the rectangle can be expressed by the equation y = x2 + 4x. What is a reasonable domain for this function? A
y > 0

B
y > 4

C
x > 0

D
x > 2

When talking about object measurements, we usually require they be positive.

A suitable domain is x > 0.

(and somewhat less than any substantial fraction of the Earth's dimensions. The numerical value will depend on the chosen units.)

Step-by-step explanation:

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
