Answer:
perimeter = 6x+15
Step-by-step explanation:
Just subtract and then add then you should get your answer.
Cos(2x) = cos^2(x) - sin^2(x) - cos(x)
but sin^2(x) = 1 - cos^2(x)
cos(2x) - cos(x) = cos^2(x) - (1 - cos^2(x) ) - cos(x)
cos(2x) - cos(x) = cos^2(x) - 1 + cos^2(x) - cos(x)
cos(2x) - cos(x) = 2cos^2(x) - 1 - cos(x)
cos(2x) - cos(x) = (2cos(x) + 1)(cos(x) - 1)
I think this is what you have asked for.
Answer:13.1
Step-by-step explanation:
Area equation:S=
Answer:
9
Step-by-step explanation:
they said that m=6 which you can plug in into the problem, now that you know what 'm' is. It will look like this:
6/2 + 6 = ?
6 divided by 2 = 3 so it'll look like this
3 + 6 = 9
