The answer is 9a+5. All you have to do is combine like terms:)
# 12 should be the last one
Answer:
Inverse = (arcos x) / 2.
Step-by-step explanation:
y = cos 2x
2x= arcos y
x = (arcos y) / 2.
Inverse = (arcos x) / 2.
In this question, we have to fin the line of intersection of the planes A and QRV.
We have to see the given figure and find the line on which the two planes A and QRV meets.
Lines SR,TS, WT and WQ are not on plane QRV.
The only line which passes through both planes is QR.
And that's the line of intersection of the two planes.
4n+6=4+2+4n, well first combine like terms, 4n+6=6+4n and those are exactly the same, there's no magical n that can make 4n+6 not equal 4n+6, so <span>many
