Answer:
4800
Step-by-step explanation:
A day consist of 24 hours. Half of 24 is 12. 4 x 13 = 12 so 1600 x 3 = 4800.
Hey You!
You must use multiplication and subtraction to solve:
3 × 12 = 36
2 × 6 = 12
36 - 12 = 24
You will pay $24 more.
Answer:
![2(3r-2)(r+3)](https://tex.z-dn.net/?f=2%283r-2%29%28r%2B3%29)
Step-by-step explanation:
Factor ![6r^2+14r-12](https://tex.z-dn.net/?f=6r%5E2%2B14r-12)
![6r2+14r-12](https://tex.z-dn.net/?f=6r2%2B14r-12)
![=2(3r-2)(r+3)](https://tex.z-dn.net/?f=%3D2%283r-2%29%28r%2B3%29)
Differences:
If the a≠1, then instead of finding two numbers that when multiplied equal c and when added equal b (which is the a=1 situation), you are looking for two numbers which when multiplied equal ac and add up to be b.
When finding the two numbers for a≠1, you cannot just plug the two numbers into (x+__)(x+__), you have to extend the b term into those two numbers.
After extending the b term into the two terms, you then have to group them and take out the GCF's unlike in an a=1 situation.
Similarities:
The first step for both is finding two terms which equal b if added.
Once factored, you have to set the factored sections to zero if you wish to find the solutions.
Before finding the two terms which equal b if added, you should take out any GCF's from the overall equation.
