Answer:
18(p-2)
Step-by-step explanation:
We want to factor 
We know that the greatest common factor is 18.
So we can rewrite to obtain:
We factor the GCF to obtain:
Therefore 
Therefore the equivalent expression to 18p-36 is 18(p-2)
Just take the coordinates of both those red dots and use the slope formula: y2-y1 all divided by x2-x1. that should give you slope
The translation is (x-4, y+15)
This means you would subtract 4 from the X coordinate and add 15 to the y coordinate.
The original coordinates is (9,-8)
The first number is X and the 2nd number is Y.
9-4 = 5
-8+15 = 7
The new location would be (5,7)
The answer is B.
Answer: at 11:54
Step-by-step explanation:
Let's define the 10:30 as our t = 0 min.
We know that Train A stops every 12 mins, and Train B stops every 14 mins, they will stop at the same time in the least common multiple of 12 and 14.
To find the least common multiple of two numbers, we must do:
LCM(a,b) = a*b/GCD(a,b)
Where GCD(a, b) is the greatest common divisor of a and b.
In this case the only common divisior of 12 and 14 is 2.
So we have:
LCM(12, 14) = 12*14/2 = 84.
Then the both trains will stop 84 minutes after 10:30
one hour has 60 mins, so we can write 84 minutes as:
1 hour and 24 minutes = 1:24
Then they will stop at the same time at 10:30 + 1:24 = 11:54
