Answer: 10511
The reason being you need to convert 63% to a decimal which would be 0.63
Then you would multiply 0.63 * 16684
And then you would get 10510.92 but you would up because you cannot have .9 of a fan

Answer:
AB = √116 ≈ 10.77
Step-by-step explanation:
Use the formula that calculate the distance between two points:
![L = \sqrt{(x_{2} - x_{1})^{2}+(y_{2} - y_{1})^{2}}](https://tex.z-dn.net/?f=L%20%3D%20%5Csqrt%7B%28x_%7B2%7D%20-%20x_%7B1%7D%29%5E%7B2%7D%2B%28y_%7B2%7D%20-%20y_%7B1%7D%29%5E%7B2%7D%7D)
L means length
For the x and y, substitute a coordinate value that you will label as set 1 or 2.
For example:
A (-3, 7) will be set 1. x₁ = -3 y₁ = 7
B (7 , 3) will be set 2. x₂ = 7 y₂ = 3
Substitute the points into the formula to find the length AB. Simplify.
![L = \sqrt{(x_{2} - x_{1})^{2}+(y_{2} - y_{1})^{2}}](https://tex.z-dn.net/?f=L%20%3D%20%5Csqrt%7B%28x_%7B2%7D%20-%20x_%7B1%7D%29%5E%7B2%7D%2B%28y_%7B2%7D%20-%20y_%7B1%7D%29%5E%7B2%7D%7D)
Solve inside the brackets first
Square each term under the root
Add under the root
Final exact answer is radical (root) form
Final approximate or rounded answer to 2 decimals
The length of AB is the squareroot of 116, or about 10.77 units.
First line because 4(2a+1)=8a+4 and 9a+4-(8a+4)= a
Second line because a times 2 =2a and 2a+1-2a=1
<span>Although the second equality is more or less obvious since 2a+1 leaves a remainder of 1 when divided by a.</span>
