Area of a rectangle = Length x Breadth
or
Breadth = Area / Length = 3x^2 + 5x / x = x(3x + 5)/x = 3x + 5
Hope this helps.

The area is length times width.
Substitute:
3x^2 + 5x = x * width.
Everything has an x in it, so factor out the x.
(3x + 5) * x = x * width
Divide both sides by x
3x + 5 = width.
And that's your answer.

Area = length * width
3x² + 5 = x * width
width=(3x²+5)/x = 3x + x/5

The area of a rectangle is 3x^2 + 5x.
The length is x.
x can take on any positive value as there are no restictions on it; therefore, the area can take on any value.
Thus the width can be any positive real value.

L X W = Area
x X W = 3x² + 5x
W = (3x² + 5x) / x
W = 3x + 5
