It’s a quadratic function
C-b=6
solve for c
c=b+6
substitute b+6 for c
b+c=10
b+(b+6)=10
2b=4
b=2
substitute that in to find C
c-b=6
c-2=6
c=8
a+b+c=18
a+2+8=18
a+10=18
a=8
so a=8, b=2, c=8
Answer:
37m (hope im doing it in right way)
Step-by-step explanation:
<h3>
![{35}^{2} + {12}^{2} = 1369](https://tex.z-dn.net/?f=%20%7B35%7D%5E%7B2%7D%20%20%20%2B%20%20%7B12%7D%5E%7B2%7D%20%20%3D%201369)
</h3>
![x = \sqrt{1369}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Csqrt%7B1369%7D%20)
![x = 37m](https://tex.z-dn.net/?f=x%20%3D%2037m)
Mean is when you add all of them together and divide by the amount of data you collected. Mean is considered the average. So, all of them added together would be 14. Divide that by 7. You should get 2 and that is the average.
