3:40
1:13
it would be 13.3 repeated but since you round to the nearest dollar it would be 13. All I did was divide 40 by 3.

Answer:
8x^2-34x+35
Explanation:
Cos² 2x = (1+cos 4x )/2
cos² 6x = (1+cos 12x)/2
subtract to get 1/2 (cos 4x - cos 12x )
= 1/2 (2 sin 4x sin 8x ) as cos A - cos B = 2 [ sin (A+B)/2 sin (A-B)/2 ]
so the answer
