Answer:
Step-by-step explanation:
x^2 + 3x - 9 =0
By comparing with the equation ax^2+bx+c = 0,
we get,
a = 1, b=3, c = -9
we know the formula for x is,
x = (-b±√(b^2 - 4ac))/2a
x = (-3±√45)/2
x = (-3±3√5)/2
x = (-3+3√5)/2, (-3-3√5)/2
For this case, what you should see is which lines contain point O.
We have then that the lines that contain this point are:
EC
AD
BO
We note that three lines contain point O.
Therefore, three lines intersect at the same point.

Answer:
2 hours.
Step-by-step explanation:
1 1/2 hours is equal to 90 minutes. We can calculate from this that 1/4 of the movie is equal to 30 minutes. To get the answer, we add the missing 1/4 of the movie (equal to 30 minutes) to get a total of 120 minutes, which is equal to two hours.
Good luck! Hope this helped!
