1) expand csc and cotx identity
(1/sinx)-sinx = (cosx/sinx)*(cosx)
2) get common denominator on the left side
(1-sin^2x)/(sinx)= (cos^2x)/sinx
3) using cos^2x+sin^2x=1 you finished
cos^2(x)/sinx= cos^2(x)/sinx
hope that helps<span />
6x^2 - 19x - 55 = 6x^2 -30x + 11x - 55 = 6x(x - 5) + 11(x - 5) = (6x + 11)(x - 5)
Hopes This Helps you!

Made a 100% on the test
Answer:
It is 4x + 4y.
Step-by-step explanation:
All you have to do is add all of the y's toghther and then add all of the x's toghther.
F(x) can be written as:
f(x) = Asin(2x); where A is the amplitude and the period of the function is half that of a normal sin function.
f(π/4) = 4
4 = Asin(2(π/4))
4 = Asin(π/2)
A = 4
Amplitude of g(x) = 1/2 * amplitude of f(x)
A for g(x) = 2
g(x) = 2sin(x)
