0=-8x-4
you then move the variable to the left and you get
8x=-4
you then divide both sides to get the answer
x=-1/2
Answer:

Step-by-step explanation:
The given expression is : 
We need to simplify the above expression.
We know that, 
or

So, the simplified form of the given expression is
. Hence, the correct option is (A).

Sorry that's all i know
<h3>that is in my answer</h3>

Protons is the answer that makes the most sense
Using relations in a right triangle, considering c as the hypotenuse, we have that the length of side A is: 
<h3>What are the relations in a right triangle?</h3>
The relations in a right triangle are given as follows:
- The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
- The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
- The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.
From the information given, we can build the following relation:
cos(A) = a/c.
