Step-by-step explanation:
(2 cos(2x)) / (cot x – tan x)
Multiply top and bottom by sin x cos x:
(2 cos(2x) sin x cos x) / (cos² x – sin² x)
Use double angle formula:
(2 cos(2x) sin x cos x) / (cos(2x))
2 sin x cos x
Use double angle formula:
sin(2x)
Answer:
Answer in explanation section
Step-by-step explanation:
8(2x-14)+13=4x-27. Given
16x-112+13=4x-27. Distributive property
16x-99=4x-27. Simplify
14x-99=-27. subtract
14x=72. Subtract
x=36/7. Divide to get x
The answer is 4,239,000 but I don’t know what you mean by decimal form.
30.2
because if on a caluculator it says ;-;
easy!
