-3x² - 9x = 0
Divide each side of the equation by -3 :
x² + 3x = 0
Factor the left side:
x (x + 3) = 0
This is true if x=0 or if x=-3 .

Answer:
D -1
Step-by-step explanation:
3(x+1) = 2(x-1)
Use distributive property and get;
3x+3 = 2x-2
Add 2 to both sides,
3x+5 = 2x+4
Subtract 2x from both sides
1x+5 = 4
Subtract 5 from both sides
1x=-1
x = -1

Step-by-step explanation:
If Ben practices this way every day, then the amount of time should be the same.
20 minutes of song practice, 15 minutes of scale practice.
20+15=35
multiply the 35 minutes per day by three
35 times 3 equals 105
So the answer is C.
3 × (20 + 15)
3(35)=105
Answer:
C. 3 x (20 + 15)
Step-by-step explanation:
You have to add 20 + 15 to get 45 so the 20 + 15 goes in the (). It says how much time he has practiced in 3 days so you have to multiply the things in the () by 3 so the 3 goes out side the ().

Final answer:
In the analogy posed in the question, 'ready' is to 'prepared' as 'unmindful' is to 'neglectful'. That is, just as being ready is synonymous with being prepared, being unmindful is synonymous with being neglectful.
Explanation:
In English language, there is a type of analogy where a pattern of word pairs is presented and the pattern is to be completed with another pair of words that follows the same relation. In your question, 'ready is to prepared as unmindful is to....', therefore, we are trying to find a word that is to 'unmindful' as 'prepared' is to 'ready'.
When someone is 'ready', it means they are 'prepared'. In a similar way, when someone is 'unmindful', it means they are 'unprepared' or 'neglectful'. Therefore, 'unmindful is to neglectful' is the correct analogy to the given question, following the same pattern as the 'ready-prepared' analogy.

Final answer:
The question seeks to find a word that is to 'unmindful' as 'ready' is to 'prepared'. This is looking for a word that shares a similar relationship, in this case, the word 'negligent'.
Explanation:
The question is a form of analogy or comparison where you are asked to find a word that is to 'unmindful' as 'ready' is to 'prepared'. In other words, you are looking for a word that has a similar relationship to 'unmindful' as 'prepared' does to 'ready'. When you are 'ready' you are 'prepared'. Therefore, when you are 'unmindful' you can be seen as being 'negligent' because both words signify a lack of attention or thoughtfulness.
