Whats the question
The answer to this question would be 152,000
In this question, you are given multiple number names and asked to add it. To answer this question, it will be easier to split the sentences into multiple parts like this:
<span>1. "14 ten thousands" mean 14 * 10,000 =140,000
</span><span>2. "12 thousands" mean 12 * 1,000= 12,000
Then, if you add them up it will be: 140,000+ 12,000= 152,000</span>
<u>Answer:</u>
<u>Step-by-step explanation:</u>
- Perimeter: 2B + 2L
- => 2(3n - 7) + 2(n + 5)
- => 6n - 14 + 2n + 10
- => 8n - 4
<u>Conclusion:</u>
Therefore, the perimeter in terms of n is 8n - 4.
Hoped this helped.
Answer:
y = -(x + 5)² + 4
Step-by-step explanation:
The roots are -3 and -7, so:
y = a (x + 3) (x + 7)
Distribute and complete the square:
y = a (x² + 10x + 21)
y = a (x² + 10x + 25 − 4)
y = a (x² + 10x + 25) − 4a
y = a (x + 5)² − 4a
The vertex is (-5, 4), so a = -1.
y = -(x + 5)² + 4
Answer:
A. 175,760,000
B. 156,000,000
Step-by-step explanation:
For part A:
There are 26 letters in the alphabet. Therefore, if there are 3 spots to use 26 letters, that is represented as 
. As for numbers, there are 10 digits from 0-9. So if there are 4 spots for numbers, the total possible number of sequences is 
. So you simply multiply and to get 175,760,000 possible combinations.
For part B:
If the same letter can't be repeated, instead of using an exponent, we have to use a factorial, but only for the 3 digits required in the license plate. These are called permutations and can be expressed as 
, which is the same as saying 26 x 25 x 24. Since there is no change to number of numbers, that remains the same.
