Question

Rae wants to dig the foundation for a secret lair. They want the lair to be rectangular,

6 feet longer than it is wide. Write the equation Rae should use to determine the
width of a pen which has an area of 280 square feet.

Answer 1

x² + 6x - 280 = 0

Explanation:

Let x = width.

Then, x + 6 = length.

area = length × width

280 = (x + 6)x

x² + 6x - 280 = 0
