multiply them
take m on one side
The answer is 2 dogs.
You would divide 100 by 5. This will give you 20 then divide the percentage (40%) by 20 and it give you 2.
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
Using distributive property, it would become 14x.
