Which statement about the following equation is true? 3x^2 - 8x + 5 = 5x^2

The discriminant (d) of the equation expressed as ax² + bx + c = 0 may be calculated by,
                                      d = b² - 4ac
Simplifying the equation, -2x² - 8x + 5 = 0. Substituting the known values,
                                d = (-8)² - 4(-2)(5) = 104

The answer is letter B. The discriminant is greater than 0, so there are two real roots. 

16 km due west

Step-by-step explanation:

The bearing of the school p from school q is 16 km due west.

To find the bearing of school q from school p, we have to find the direction that the school q is with respect to school p.

Since p is directly west of q, then it implies that q must be directly east of p.

We now know the direction.

Since the distance from q to p is exactly the same as the distance from p to q, then, the distance from p to q is 16 km.

Hence, the bearing of q from p is 16 km due west.
