Answer:
K still the same value
Step-by-step explanation:
given a reaction aA+bB<->cC+dD the constant K is defined as:
K is a constant so it won't change the value. Instead, the values of C and D are going to change. The position of equilibrium moves because of the need to keep a constant value for the equilibrium constant.
Factor by using the rational roots test, and find that -2 is a root.
Replace X with -2 and simplify each term.
Divide the polynomial by (x+2)
The final answer becomes x = -2 and x = -1/2 +/-√3/2i
The first choice is the correct one.
Answer:
13 to 25
13:25
Step-by-step explanation:
All of these show the ratio 13/25
Hope this helps!
Three and a half divided by seven-eighth equals seven over two times eight over seven equals fifty over fourteen equals four
Based on the definition of congruent angles, the value of x is: 23.
<h3>What are Congruent Angles?</h3>
Congruent angles have the same measure. Examples of angles that are congruent are:
- Alternate interior angles
- Alternate exterior angles
- Corresponding angles
Thus:
(5x + 16) = (6x - 7) -- congruent angles
Combine like terms
5x - 6x = -16 - 7
-x = -23
x = 23
Therefore, based on the definition of congruent angles, the value of x is: 23.
