Answer:
x = -3 or x = -5/3
Step-by-step explanation:
Solve for x over the real numbers:
(x + 3) (3 x + 5) = 0
Split into two equations:
x + 3 = 0 or 3 x + 5 = 0
Subtract 3 from both sides:
x = -3 or 3 x + 5 = 0
Subtract 5 from both sides:
x = -3 or 3 x = -5
Divide both sides by 3:
Answer: x = -3 or x = -5/3

Answer:
6-hours
D = C + T
Step-by-step explanation:
The following equations represent the total distance travelled by each vehicle, the truck (C) and the Train (T) where x is the amount of time travelling in hours...
C = 45x
T = 60x
Since the truck traveled 2 hours longer than the train we can add this value to the variable x in the truck's distance equation and then make both equations equal one another to calculate the number of hours before they cover the same distance...
45(x+2) = 60x ... distribute 45 evenly
45x + 90 = 60x ... subtract 45x from both sides
90 = 15x ... divide both sides by 15
6 = x
Finally, we can see that both vehicles would have traveled the same distance at the 6-hour mark. Now to calculate the total distance traveled (D) we can use the following equation...
D = C + T
