A scaler quantity is measured solely on its magnititude (size) and it lacks a direction. A vector, however, is measured on both its magnitude and direction. Examples of scalers are time and temperature because they only consist of a magnitude, but have no direction associated with them. Examples of vectors are velocity, acceleration, and force, because they consist of both a magnitude and a direction.

Answer:
It’s 729
Step-by-step explanation:
Start with expressions in blue boxes:
1st column) ![36x+9;](https://tex.z-dn.net/?f=36x%2B9%3B)
2nd column) ![9(4x-1)=36x-9;](https://tex.z-dn.net/?f=9%284x-1%29%3D36x-9%3B)
3rd column) ![(4\cdot 9x)+(4\cdot 2)=36x+8.](https://tex.z-dn.net/?f=%284%5Ccdot%209x%29%2B%284%5Ccdot%202%29%3D36x%2B8.)
You have 6 expressions. Consider all them:
1.
- 3rd column;
2.
- 1st column;
3.
- 2nd column;
4.
- 1st column;
5.
- 2nd column;
6.
- 3rd column.
A triangle has to add up to 180 degrees, so
106 + 48 = 154
180 - 154 = 26
ANSWER: 26 degrees
This should be right and I hope it helps :)
Start by adding 2 to both sides to get 3r^2 = 48. then divide both sides by 3 to get r^2 = 16. square root both sides to get r = 4.
