Using trigonometry property, the best option is B.
What is trigonometry?
Trigonometry deals with "the relationship between the sides and the angles of triangles".
According to the question,
[tan x + cot x] (sin x + cos x) = 1
[tan x =
and cot x =
]
[By cancellation law]
By the Pythagoras theorem, .
Hence, using trigonometry property, the best option is B.

(2x - 1)(x + 6) = 0
becomes
2x*x+2x*6+-1*x+-1*6
which simplifies to
2x^2 + 12x - x - 6
and then we add like terms to get
2x^2 + 11x - 6
now that it is in the correct form we can identify "a" "b" and "c" by following this form
ax^2 + bx + c
looking back at the equation we got earlier
2x^2 + 11x - 6
a=2,b=11,and c=-6
Answer:
The answer is b=11

Answer:
Step-by-step explanation:
The given parallelogram is attached.
First, we have to define some terms:
- Collinear means that they are on the same line, non-collinear is the opposite.
- Intersecting means that the point are touching each other, this apply to segments.
- Parallel means that they will never intersect, because they have the same slope or inclination, this apply to lines also.
- Coplanar means that points are in the same plane, non-coplanar is the opposite.
So, if we observe points D, G and J, from given options, they are non-collinear and non-coplanar, because they are not on the same line, nor plane.

Answer:
See below.
Step-by-step explanation:
x < -2 means that x is any number that is less than -2.
Is -2 less than -2? Answer: No.
A number is equal to itself. A number is not greater than itself or less than itself.
When the solution to an inequality is x < -2, the only values of x that are valid are numbers less than -2. -2 itself is not a valid solution.
