2cos^2 x = 1 + cos 2x
cos^2 x = 1/2(1 + cos 2x)
f(x) = 6cos^2 x - 4 sin 2x = 6(1/2(1 + cos 2x) - 4 sin 2x = 3 + 3cos 2x - 4sin 2x
5/4=15/12
2/3=8/12
15/12+8/12=23/12
C! 80 + 10 is 90, 90+90 is 180. There are 180 degrees in one triangle
your answer would be b becuase that is 3/6 so thats half and ou would simply it and 1/4 do the same
25.65 ÷ 15 = 1.71
So, the answer to this problem is 1.17
