Answer:
Step-by-step explanation:
Let x represent the width of the rectangular box.
The length is 5ft longer than twice the width x. This would be expressed as
2x + 5
The formula for determining the volume of a rectangular box is expressed as
Volume = length × width × height.
If the height of a rectangular box is 7ft and the volume is 714ft cubed, then the the equation in terms of x that represents the given relationship would be
7 × x × (2x + 5) = 714
7x(2x + 5) = 714
14x² + 35x = 714
14x² + 35x - 714 = 0
