After simplifying the trigonometric expression 2 cos (3 x) sin (3 x), we get the value as sin (6 x).
We are given the expression as:
2 cos (3 x) sin (3 x)
Now, we know the trigonometric identity as:
2 sin θ cos θ = 2 sin (2 θ)
Using this identity in the expression where θ = 3 x, we get that:
2 cos (3 x) sin (3 x) = sin ( 2 × 3 x) ( value of θ substituted in the expression)
2 cos (3 x) sin (3 x) = sin (6 x)
Therefore, after simplifying the trigonometric expression 2 cos (3 x) sin (3 x), we get the value as sin (6 x).

Answer:
-5.5
Step-by-step explanation:
2.75+(-2)+(-6.25)=-5.5
Answer:
A 2 term polynomial 3x^2-3
Y=mx+b
lines are parallels so m=2
y=2x+b
line passing through the point (4,2), so x=4 y=2
put these value in equation
2=2*4+b
2=8+b
b=2-8
b=-6
y=2x-6
Answer: y=2x-6

I’m not sure if this is how you do it but:
2(8a - 12)
4(4a - 6)
8(2a - 3)
