Answer:
((1 × 2) + 3) × 4 × 5 + 6 - 7 - 8 + 9 = 100
Step-by-step explanation:
((1 × 2) + 3) × 4 × 5 + 6 - 7 - 8 + 9 = 100
= (2+3) x 4 x 5 + 6 - 7 - 8 + 9
= 5 x 4 x 5 + 6 - 7 - 8 + 9
= 100 + 6 - 7 - 8 + 9
= 115 - 7 - 8
= 115 - 15
= 100
First we need to find the missing side, use
![a = \sqrt{ {c}^{2} - {b}^{2} }](https://tex.z-dn.net/?f=a%20%3D%20%20%5Csqrt%7B%20%7Bc%7D%5E%7B2%7D%20-%20%20%7Bb%7D%5E%7B2%7D%20%20%7D%20)
So the missing leg = the sqrt of the hypotenuse squared minus the other leg squared.
Let's substitute the numbers,
![a = \sqrt{ {10}^{2} - {6}^{2} }](https://tex.z-dn.net/?f=a%20%3D%20%20%5Csqrt%7B%20%7B10%7D%5E%7B2%7D%20%20-%20%20%7B6%7D%5E%7B2%7D%20%7D%20)
Solve for the squares,
![a = \sqrt{100 - 36}](https://tex.z-dn.net/?f=a%20%3D%20%20%5Csqrt%7B100%20-%2036%7D%20)
Subtract,
![a = \sqrt{64}](https://tex.z-dn.net/?f=a%20%3D%20%20%5Csqrt%7B64%7D%20)
Solve for the root,
![a = 8](https://tex.z-dn.net/?f=a%20%3D%208)
~~
So our missing length is 8.
To find the perimeter of the triangle, simply add all the sides....
~~
![8 + 10 + 6 = 24](https://tex.z-dn.net/?f=8%20%2B%2010%20%2B%206%20%3D%2024)

The second ball would most likely be red and there are 5 red balls in the bag. And if you replaced the ball it would most likely be the same ball.
