The answer Is 2/12 because if u multiply 1 x2 it is 2 then 3 x4 which is 12
Hi there!

Use the chain rule:
f(g(x)) = f'(g(x)) · g'(x)
Thus:
dy/dx sin(x) = cos(x)
dy/dx cos(x) = -sin(x)
Use the chain rule format:
f(x) = sin(x)
g(x) = cos(x)
cos(cos(x)) · (-sin(x))
-sin(x)cos(cos(x))
Answer:its algebra very simple all you want do is get x by itself
Step-by-step explanation:
you have to subtract from both sides 1
so then you'll have
4 x = (1 - x)
after that you divide by 4 from both sides you'll be left with
x = 1 - x
