The resulting polynomial when 5x -6 is subtracted from 3x² -6x +2 is; 3x² -11x +8.
<h3>What is the result of the polynomial subtraction?</h3>
It follows from the task content that the polynomial 5x -6 is to be subtracted from 3x² -6x +2.
Hence, the subtraction goes thus; 3x² -6x +2 -(5x-6).
Hence, 3x² -6x +2 -5x+6
= 3x² -11x +8.

The population after 3 years would be 8.20 millions.
Step-by-step explanation:
Given,
Initial population = I = 4.2 million
Growing rate = r = 25%
If the initial population and growing rate is given, the formula to calculate the population (x) after n years would be:
![x = I * (1 + \frac{r}{100} )^{n}](https://tex.z-dn.net/?f=x%20%3D%20I%20%2A%20%281%20%2B%20%5Cfrac%7Br%7D%7B100%7D%20%29%5E%7Bn%7D)
By putting the values in the equation, we get
![x = 4.2 * (1 + \frac{25}{100} )^{n}](https://tex.z-dn.net/?f=x%20%3D%204.2%20%2A%20%281%20%2B%20%5Cfrac%7B25%7D%7B100%7D%20%29%5E%7Bn%7D)
The population after 1st year (x1) would be
![x1 = 4.2 * (1 + \frac{25}{100} )^{1}](https://tex.z-dn.net/?f=x1%20%3D%204.2%20%2A%20%281%20%2B%20%5Cfrac%7B25%7D%7B100%7D%20%29%5E%7B1%7D)
x1 = 5.25 million
Similarly,
![x2 = 4.2 * (1 + \frac{25}{100} )^{2}](https://tex.z-dn.net/?f=x2%20%3D%204.2%20%2A%20%281%20%2B%20%5Cfrac%7B25%7D%7B100%7D%20%29%5E%7B2%7D)
x2 = 6.56 million
![x3 = 4.2 * (1 + \frac{25}{100} )^{3}](https://tex.z-dn.net/?f=x3%20%3D%204.2%20%2A%20%281%20%2B%20%5Cfrac%7B25%7D%7B100%7D%20%29%5E%7B3%7D)
x3 = 8.20 million
Hence, the population after 3 years would be 8.20 millions.
But, if you are asking about the total population at that time. It would be
I + x1 + x2 + x3 = 24.21 million
Answer:
Her grocery bill is $4.62
Step-by-step explanation:
The first step is to multiply 6 and .43 to get how much it was for all of the apples.
Then the next step is to do the same thing with the oranges.
Then the last step is to add the two together.
