6x^2 - 8 = 4x^2 + 7x
6x^2 - 4x^2 - 7x - 8 = 0
2x^2 - 7x - 8 = 0
discriminant = b^2 - 4ac; where a = 2, b = -7 and c = -8
d = (-7)^2 - 4(2)(-8)
d = 49 + 64
d = 113

the discriminant is greater than zero, so there are two real roots

The area of the patio is 216 square feet. Write an equation that represents the area of the patio
Hoochie [10]

Answer:

216=2w \times w

Step-by-step explanation:

Assuming that the patio is a rectangle, we have

A= l\times w

Where l is the length and w is the width.

Now let's assume that the length of the patio is double than the width.

l=2w

So, the equation that represents this problem is

216=2w \times w
