First, I would factor f(x) and g(x).
f(x)=2x(2x+3)
g(x)=(2x+3)(x+5)
Then divide.
(f/g)(x)=
Cancel out (2x+3)
you are left with 2x/(x+5)
f(x)=2x(2x+3)
g(x)=(2x+3)(x+5)
Then divide.
(f/g)(x)=
Cancel out (2x+3)
you are left with 2x/(x+5)
For the given triangle, the cosine of angle A equals .
Step-by-step explanation:
Step 1; In the given triangle, the opposite side has a length of 9 units, the adjacent side has a length of 3√3 units while the hypotenuse of the triangle measures 6√3 units. To calculate the cosine of angle A we divide the adjacent side by the hypotenuse side.
cos A = .
Step 2; Length of the adjacent side = 3√3 units.
Length of the hypotenuse side = 6√3 units.
cos A = 3√3 / 6√3
cos A = .
To check we also have A = 60° and cos 60° = .
