LCM stands for Least Common Multiple.
The LCM of two numbers is the lowest number that can divide into the two original numbers.
For most numbers, you can find the LCM by simply multiplying the two numbers:

The LCM of 7 and 13 is 91.
Why? Because all you have to do is find it's multiple.
7 x 13
OR
7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91.
13: 13, 26, 39, 52, 65, 78, 91.
Answer:
A
Step-by-step explanation:
It is not B because 7x^2 means multiplying the equation by seven. It isn't C because that would move the graph DOWN seven units. And it's not D because when it is in parenthesis like that, it means that it is a horizontal shift, not vertical.
For the first city, the 95% confidence interval would be:
28,900 +/- 2300 x 3 = 28,900 +/-6900$
For the second city, the 95% confidence interval would be:
30,300 +/- 2100 x 3 = 30,300 +/- 6300$
C. 1,315.06
