Answer
Subtract
from ![-2x^2 -15xy+9y^2](https://tex.z-dn.net/?f=-2x%5E2%20-15xy%2B9y%5E2)
then;
![-2x^2 -15xy+9y^2 - (7x^2 -5xy+8y^2)](https://tex.z-dn.net/?f=-2x%5E2%20-15xy%2B9y%5E2%20-%20%287x%5E2%20-5xy%2B8y%5E2%29)
Remove the bracket we have;
![-2x^2 -15xy+9y^2 - 7x^2 + 5xy - 8y^2](https://tex.z-dn.net/?f=-2x%5E2%20-15xy%2B9y%5E2%20-%207x%5E2%20%2B%205xy%20-%208y%5E2)
Like terms are those terms which have same variable to the same power.
Combine like terms;
![-9x^2 -10xy+y^2](https://tex.z-dn.net/?f=-9x%5E2%20-10xy%2By%5E2)
Therefore, Subtracting
from
we get ![-9x^2 -10xy+y^2](https://tex.z-dn.net/?f=-9x%5E2%20-10xy%2By%5E2)
Answer:
Roughly 16 million bacteria.
Step-by-step explanation:
Multiply the rate of the bacteria going through mitosis times the amount of daughter cells per hour, for this case.
<em>r x (m)ms x hr</em> <em>= </em>bacteria in one day
Hope this helps!
<em>note: ms and hr are millisecond and hour</em>
