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:
110.06
Step-by-step explanation:
Make a ratio: 95.20 / x = 86.5 / 100 (86.5 = 100% - 13.5%)
Cross multiply: 95.20 x 100 = 86.5x
9520 = 86.5x
110.06 = x
