Answer:
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: 2ayx4a
Step-by-step explanation:
1) First, we will need to simplify each equation:
4ax2y = 8axy
8axy = 8axy
2ayx4a = 8ayx4a
ax8y = 8axy
2) We can now see that 2ayx4a is not the same as the others.
