Answer:
x=4200
Step-by-step explanation:
10x=42000
x=4200
distance = speed * time
the first bus speed = x
second bus = x - 12
the sum of distance = 765 miles
first distance = 6x
second distance = 6 (x -12)
6x + 6(x-12) = 765
x + x -12 = 127.5
2x = 139.5
x = 69.75 mi/h which is the faster bus
the second bus speed = 57.75 mi/h
What multiplies to 25 and adds to -10
-5 and -5
(x-5)(x-5)
(x-5)²
