Could anyone please help me? I really need help, I am not understanding this. I will love the help, please.
Ratling [72]

Answer:

Problem 1: Even

Problem 2: Even

Problem 3: Neither

Problem 4: Neither

Explanation:

You have to consider the fact that just because it is negative doesn't mean its odd. You have to do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

Hope this helps! :)

In a closed system a reversible chemical reaction will reach a state of dynamic chemical equilibrium   when the rate of the forward reaction is to be in or equal to the rate of the reverse reaction.

<h3>What occurs if a reaction reaches dynamic equilibrium in a closed system?</h3>

A closed chemical system is said to attain dynamic equilibrium if the rate of the forward reaction is said to have equals the rate of the backward reaction and also the level of concentrations of products and reactants are said to be the same.

Hence, In a closed system a reversible chemical reaction will reach a state of dynamic chemical equilibrium   when the rate of the forward reaction is to be in or equal to the rate of the reverse reaction.

I need to solve for angle A, a quick response would be appreciated!
Firlakuza [10]

Answer:

x = 21

The two remaining angles must add to 90 degrees since a triangle adds to 180

3x+6 +x = 90

4x+6 =90

4x = 90-6

4x = 84

Divide by 4

4x/4 = 84/4

x = 21
