Answer:
![||AB|| = 11.8743](https://tex.z-dn.net/?f=%7C%7CAB%7C%7C%20%3D%2011.8743)
Step-by-step explanation:
Distance between two points:
Suppose that we have two points,
and
. The distance between them is given by:
![D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}](https://tex.z-dn.net/?f=D%20%3D%20%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%2B%28z_2-z_1%29%5E2%7D)
Distance from A(-8,-3,-2) and B(-4,8,0)
![||AB|| = \sqrt{(-4-(-8))^2+(8-(-3))^2+(0-(-2))^2}](https://tex.z-dn.net/?f=%7C%7CAB%7C%7C%20%3D%20%5Csqrt%7B%28-4-%28-8%29%29%5E2%2B%288-%28-3%29%29%5E2%2B%280-%28-2%29%29%5E2%7D)
![||AB|| = \sqrt{4^2 + 11^2 + 2^2}](https://tex.z-dn.net/?f=%7C%7CAB%7C%7C%20%3D%20%5Csqrt%7B4%5E2%20%2B%2011%5E2%20%2B%202%5E2%7D)
![||AB|| = 11.8743](https://tex.z-dn.net/?f=%7C%7CAB%7C%7C%20%3D%2011.8743)
No, because x/2 divides x by two, while -2x multiplies x by -2.
Answer:
![\Large \boxed{b=2}](https://tex.z-dn.net/?f=%5CLarge%20%5Cboxed%7Bb%3D2%7D)
Step-by-step explanation:
-5+2(10b-2)=31
Expand brackets.
-5+20b-4=31
-9+20b=31
Add 9 on both sides.
20b=40
Divide both sides by 20
b=2
B^n+5
When multiplying exponents the numbers are added
