Just email your teacher and ask if you can raise your grade because you can’t do your work due to co-vid
2 x 2 x 5 = 20
4 x 2 x 2 = 16
20 + 16 = 36
Ans: 36 cubic feet
Answer:
2x
Step-by-step explanation:
Since Jamie and Ana have the same age, they are both x years old. So x+x=2x.
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
