Answer:
8sin(x)cos³(x)
Step-by-step explanation:
sin(4x) +2 sin(2x) = 2sin(2x)*cos(2x) + 2sin(2x) = 2sin(2x)(cos2x + 1)=
= 2sin(2x)(cos²x - sin²x + cos²x + sin²x)=²2sin(2x)*(2cos²x)=
= 4*2sin(x)*cos(x)*cos²(x)= 8sin(x)cos³(x)
Answer:
I don't know the answer but i recommend a website called cymath. It is a calculator to any equation and demonstrates the procedures.

Answer: taking the bus to work takes 13 minutes longer.
Step-by-step explanation:
It usually took josh 2/5 of an hour to ride his bike to work. This means that the number of hours that it took Josh to ride his bike to work is
2/5 × 60 = 24 minutes
But on Monday, his bike was broken, so he took the bus to work which took 5/8 of an hour. This means that the amount of time that it took Josh spent on the bus to work is
5/8 × 60 = 37.5 minutes
The difference between the time spent riding the bike and time spent on the bus is
37.5 - 24 = 13 minutes
