This is a difference of perfect squares which is of the form:
(a^2-b^2)
And which always factors to:
(a-b)(a+b)
In this case:
(5x-8)(5x+8)
Answer:
Temperature is measured in units of temperature.
In SI units, it is K (degrees Kelvin).
In CGS units, it is °C (degrees Celsius)
In English units, it is °F (degrees Fahrenheit)
Therefore the mean and standard deviation will be measured in the selected units for temperature.
Answer:
10: -11n^5
12: 6k^2 -6k+7
Step-by-step explanation:
Ok so what your gonna do is add or subtract the ones with the same exponent.
so -15+4= -11 since they are both n^5 you can add them so your answer is:
-11n^2
now you have 8k^2-k-5k+7-2k. so you are gonna rearrange them so the same exponents are together.(keep the sign in front in front, if no sign it is positive)
8k^2-2k^2-5k-k+7
add like exponents
6k^2-6k+7
1.539 divided by 10 which equal to 0.1539
