The answer to the question
Answer:
As Lincoln opens his speech with an allusion to the Declaration, he closes it with an allusion to the Constitution. The Preamble to the Constitution begins with the words "We the people." By using "the people," Lincoln alludes to that crucial document.
Explanation:
The value of 
is -3. 
<h2>Procedure - Differentiability</h2><h3 /><h3>Chain rule and derivatives</h3><h3 />
We derive an expression for by means of chain rule and differentiation rule for a product of functions:
![\frac{d}{dx}[f(x)\cdot g(y)] = [f'(x)\cdot \frac{dx}{dx}]\cdot g(y) + f(x) \cdot [g'(y)\cdot \frac{dy}{dx} ]](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdx%7D%5Bf%28x%29%5Ccdot%20g%28y%29%5D%20%3D%20%5Bf%27%28x%29%5Ccdot%20%5Cfrac%7Bdx%7D%7Bdx%7D%5D%5Ccdot%20g%28y%29%20%2B%20f%28x%29%20%5Ccdot%20%5Bg%27%28y%29%5Ccdot%20%5Cfrac%7Bdy%7D%7Bdx%7D%20%5D)

Hopefully I will have own my own business in a world that I have in fact changed for the better. I will work hard not only on myself but my community and environment as well.
There are different factors taken into consideration in production process. The statement that best justifies the use of the proposed modification as a way of creating an appropriate control for the investigation is that;
- The experiment can be repeated without the use of guaiacol, which will therefore show the effect of guaiacol on the reaction rates.
Oxygen is an element that exist naturally and can also be produced from different kinds of materials. This is often done by using a lot of different methods.
The natural method of getting oxygen is through photosynthesis where plants are known to use sunlight to convert carbon dioxide in the air into oxygen.
By not using guaiacol again when repeating the same experiment, one can therefore know if the guaiacol in one or different ways affect the chemical reaction of the elements.
