You add all of them together if it’s labeled with a X.
For example, the first X is 1 hour. If it has 2 Xs it would be 2 hours, if no X is shown above, it’s zero hours.
Answer is 12 hours.
Yes that is true, all opposite sides would be parallel, and all the corners are 90 degrees, then yes it is true
Answer:
![=\pm i\sqrt{66}](https://tex.z-dn.net/?f=%3D%5Cpm%20i%5Csqrt%7B66%7D)
Step-by-step explanation:
So we have:
![\pm\sqrt{-66}](https://tex.z-dn.net/?f=%5Cpm%5Csqrt%7B-66%7D)
This is the same as:
![=\pm\sqrt{66\cdot-1}](https://tex.z-dn.net/?f=%3D%5Cpm%5Csqrt%7B66%5Ccdot-1%7D)
Separate:
![=\pm\sqrt{66}\cdot\sqrt{-1}](https://tex.z-dn.net/?f=%3D%5Cpm%5Csqrt%7B66%7D%5Ccdot%5Csqrt%7B-1%7D)
Replace the second term with i:
![=\pm i\sqrt{66}](https://tex.z-dn.net/?f=%3D%5Cpm%20i%5Csqrt%7B66%7D)
The square root of 66 cannot be simplified.
So, this is our answer :)
In step 1 , it's commutative property of addition
