(x^2 + 4x + 8)(2x - 1) = 2x(x^2 + 4x + 8) - (x^2 + 4x + 8) = 2x^3 + 8x^2 + 16x - x^2 - 4x - 8 = 2x^3 + 7x^2 + 12x - 8
Answer:
either of Step 3 or Step 4
Step-by-step explanation:
At Step 3, -1 is added to both sides of the equation. Technically, this is correct (not an error), but it does not lead to a solution to the equation (so, could be considered to be an error). Adding +1 to both sides of the equation would lead more directly to a solution.
__
At Step 4, x -1 -1 is simplified to x. This is an error, as the correct simplification is x-2, so the equation after this step should read x-2 = 5. If Step 3 had been executed by adding +1 to both sides of the equation, then the simplification here would be x=7.

Answering "why" someone does something is always tricky. One can project one's own interpretation onto the actions of others, but one never really knows whether that is accurate or not.
The "why" in this case could go back to the motivation of the problem's author, which may be to see if the student can recognize that the opposite of -1 is +1, or that the sum -1-1 is not zero.
___
My guess is that Step 3 is considered to be the erroneous step, and that choosing Step 4 will get you into a losing argument with your grader.
Answer:
So the answer would be 24.15 the amount the tip is is 3.15
Step-by-step explanation:
A tip or gratuity is an extra sum of money paid to certain service workers for a provided service. Tip amounts, as well as acceptance, vary in different parts of the world. In some countries in East Asia such as Japan, tips are seen as insulting and can sometimes be interpreted as a bribe. In yet other countries such as the United States, tipping is widely expected, and in many cases, is even factored into a service worker's compensation towards satisfying the minimum wage requirement. This is important to note, since although tipping is entirely voluntary, many servers depend on tips to make a living in countries like the United States. As such, as a tourist, it can be helpful to research the tipping customs in the countries being visited. In the U.S. or any other country where tipping is expected, depending on the restaurant or the number of patrons at a table, gratuity may be automatically applied to the bill amount. As previously mentioned, tipping can be offensive in some countries, so although a citizen of the United States that is visiting another country may want to express their appreciation of the service provided, the gesture may in some cases result in the opposite effect.
Below is a map that provides some information regarding whether or not a tip is expected, or how a tip may be received in certain regions, as well as a table of typical tip amounts in the United States and Canada for different services.
Answer:
b. If n is not divisible by 2 or n is not divisible by 3, then n is not divisible by 6.
Step-by-step explanation:
Division by Six
A number is divisible by six if it is divisible by both 2 and 3.
Negation:
If the number is not divisible by either 2 or 3, it is not by 6. So the answer is given by option b.
Answer:
believe it's G, I hope that's correct for you
