What is the discriminant of the quadratic equation 4x² + x + 3 = 0?

-47

Step-by-step explanation:

For quadratic equations, the discriminant is in the format, b² - 4ac, which you would also find in the quadratic formula.

This quadratic equation is in the format ax² + bx + c, and gives you all the values you need to plug in for the discriminant.

a = 4

b = 1

c = 3

Discriminant = 1² - 4(4)(3)

= 1 - 48

= -47

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
