The way to solve is using order of operation PEMDAS. Its very easy. You should be able to solve it yourself. I'll give you the first 3 answers:
1. g/6=x
2. x=1/2u+1
3. z-m=x
I would give you all the answers but it would be best if you did it yourself. You teacher and parents would be much happier if you learnt the skill. Hope this answer helps! Mark as brainliest! :)
Answer:
Step-by-step explanation:

Answer:
A
Step-by-step explanation:
We are given:
To make it simpler and more clear, we can let u = sin(x). So:
Now, it becomes obvious that we can factor, which produces:
Cancel:
And substituting back:
Hence, our answer is A.
