Ok so first equate all the three equations whether by substituting or by eliminating then choose the one das not the answer
Use the the double angle formula:
sin(2A)=2sin(A)cos(A)
substitute 2x for A, then
20sin(2x)cos(2x)=10(sin(2(2x))cos(2(2x))=10sin(4x)
Answer:
(f ○ g)(x) = 
Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
(f ○ g)(x)
= f(g(x))
= f(x + 1)
= 
The simplified answer to that radical is attached
