6 and -2 multiplied by each other = -12 and added together = 4
A) If you only sample people in a sports supply store, your sample will be biased. People in a sports supply store are more likely to be people that belong to a gym.
B) While it does not have necessarily the same amount of bias as sampling people in the sports supply store, people that go to a park are generally more likely to be people that exercise or have a gym membership.
C) Taking a random sample of people in town is a good way to get a non-biased sample. They are not necessarily predisposed to answer your question one way or another.
D) For the same reason as choice A, this is a biased sample.
C is the best choice.

![(x + 3) {}^{2} - 16](https://tex.z-dn.net/?f=%28x%20%2B%203%29%20%7B%7D%5E%7B2%7D%20%20-%2016)
Step-by-step explanation:
![{x}^{2} + 6x - 7 = (x + 3) {}^{2} - (3) {}^{2} - 7 \\ = (x + 3) {}^{2} - 16](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%206x%20-%207%20%3D%20%28x%20%20%2B%203%29%20%20%7B%7D%5E%7B2%7D%20%20-%20%283%29%20%7B%7D%5E%7B2%7D%20%20-%207%20%5C%5C%20%20%3D%20%28x%20%2B%203%29%20%7B%7D%5E%7B2%7D%20%20-%2016)

![\boxed{\bold{LCM \ = \ 26}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cbold%7BLCM%20%5C%20%3D%20%5C%2026%7D%7D)
[ Explanation ]
-------------------------------------
LCM - The smallest number that two or more numbers can evenly fit into
- LCM - What We Know
- 2 & 13 Must Evenly Fit
- Must Be Smallest Number They Both Fit Into
- Multiple Of Two Or More Numbers
The Smallest Number That Both 2 & 13 Evenly Fit Into Is 26
26 ÷ 2 = 13
26 ÷ 13 = 2
