There would be 1 real zero and two complex zeros
So the answer is 30 packages but I did 25 times 20 = 500 and then 25 times 10 = 250
So. 30 = 750
Use the FOIL method (first, outside, inside, last) to multiply:
2x^2-8x+3x-12
This can be simplified even more into:
2x^2-5x-12.
Hope this helped!
Equal expressions can be taken equal to an another variable. The system of equations representing the equation is 
<h3>What is logarithm and some of its useful properties?</h3>
When you raise a number with an exponent, there comes a result.
Lets say you get
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
Some properties of logarithm are:

Log with base e = 2.71828... is written as
simply.
Log with base 10 is written as
simply.
The given equation is:

Adding
on both the sides, we get:

The, we get two equations as:

This is the needed system of equations.

Answer: 0.9927
Step-by-step explanation:
We assume that the number of earthquakes that occur in Los Angeles follows normal distribution.
As per given , we have

Sample size : n= 35
Let
be the sample mean.
Now ,

Hence, the probability that the mean of the sample is between 34 and 37.5. is 0.9927 .
