Answer:
.8
Step-by-step explanation:
Sin2x=2sinxcosx, cos2x=1-2sin^2x
sin(2x)+cos(3x)=2sinxcosx+cos(x+2x)
cos(x+2x)=cosx(1-2sin^2(x))-sinx2sinxcosx
sin(2x)+cos(3x)=2sinxcosx(1-sinx)+cosx(1-2sin^2(x))
Answer: 3n-6
Step-by-step explanation: You have to use the distributive property. 3 times n is 3n and 3 times -2 is -6.
