What are the solutions of 3x^2-x+4=0
guajiro [1.7K]
3x² -x+4=0

We can use quadratic formula
a=3, b= -1, c=4
 x=  \frac{-b+/- \sqrt{b^{2}-4ac} }{2a}  &#10;\\ \\ x= \frac{1+/- \sqrt{1-4*3*4} }{2*3} &#10;\\ \\ x =  \frac{1+/- \sqrt{-47} }{6} &#10;&#10;This equation does not have real  roots, it has only 2 imaginary roots.

x= \frac{1+ \sqrt{47}i }{6} &#10;\\ \\ x=  \frac{1- \sqrt{47}i }{6}

Dave walked to his friends house at a rate of 4 mph and returned biking at a rate of 10 mph. If it took him 18 minutes longer to
vesna_86 [32]

Answer:

The total distance of the round trip was 4 miles

Step-by-step explanation:

1. Let's check all the information given to answer the question correctly:

Speed of Dave walking to his friend's house = 4 mph

Speed of Dave biking from his friend's house = 10 mph

Time walking is 18 minutes longer than time biking

2. What was the total distance of the round trip?

Time walking = x

Time biking = x - 18

For solving x, we will use the following equation:

4x = 10 * (x - 18)

4x = 10x - 180

-6x = - 180

x = -180/-6 (Dividing by - 6)

x = 30

Dave walked 30 minutes and biked 12 minutes, now we can calculate the total distance, this way:

30 minutes = 0.5 hours and 12 minutes = 0.2 hours

Total distance = 4 *0.5 + 10 * 0.2

Total distance = 2 + 2

Total distance = 4 miles.
