Step-by-step explanation:
sin(2x) + cos(3x)
Use double angle formula sin(2x) = 2 sin x cos x.
Use triple angle formula cos(3x) = 4 cos³x − 3 cos x.
Substitute:
2 sin x cos x + 4 cos³x − 3 cos x
I believe what answer you have put is correct
Answer:
w is the correct answer
Step-by-step explanation:

If we choose the point (3, 0), we obtain
0 <= -1, which is not true. So we shade the region to the left of x = 4 (which is a dashed vertical line) and below
y = (1/3)x - 2 (which is a solid line).
Each guest can have 2 pounds of turkey and there would be 20 pounds of turkey left.
All you have to is subtract 35-7=28
and you get 28 chores left
