Question 78368: The area of a rectangle of lenght x is give by 3x^2+5x. Find the width of the rectangle. Answer by dolly(163) (Show Source):
You can put this solution on YOUR website! Area of the rectangle = 3x^2 + 5x
Length of the rectangle = x
Thus the width = Area/length
= (3x^2 + 5x)/x
= 3x^2/x + 5x/x
= 3x + 5
Thus the width of the rectangle = 3x + 5
