Answer:
1 hour 42 minutes
Step-by-step explanation:
Given: Speed of 1st trucker= 62 mph
Speed of 2nd trucker= 66 mph
Total distance need to cover to be in contact is 270 miles
1st trucker start 1 hour ahead of 2nd trucker
Lets assume 2nd trucker take `x` hours to be in contact and 1st trucker take `(x+1)` hours.
We know, distance=
1st trucker, distance
∴
2nd trucker, distance
∴
Now, putting the values in an equation.
⇒
Opening the parenthesis to solve and subtracting both side by 62
⇒
∴ x= = 1 hour 42 minutes
∴ It will take 1 hour 42 minutes to be able contact each other after first trucker leaves.

Answer:
(6x + 1)(x + 9)
Step-by-step explanation:
6x^2 +9 = - 55x
6x^2 + 55x + 9 = 0
55 is a pretty big number compared to either 6 or 9. Not only that, but 6*9 = 54.
So the answer is going to depend on multiply 6x together with 9
(6x + __ ) ( x + 9)
Now what goes were the underline is?
You have 54x. You need but 1 more to get 55x. So a one must go where the underline is.
(6x + 1 )(x + 9) Answer
