This is a simple example:-
x + 9
------------------------------
x - 1 ) x^2 + 8x - 9
x^2 - x subtract
------------
9x - 9
9x - 9
----------
..........
First divide x into x^2 to give x which goes above
Then multiply x - 1 by x to give x^2 - x
Subtract this fro x^2 + 8x gives 9x
Bring down the - 9 then divide x into 9x
and finally multiply x - 1 by 9 to give 9x - 9
Finally subtract and you sre done. There is no remainder as x - 1 is a factor of x^2 + 8x - 9.
The polynomial must be in descending powers of x . If one is missing you insert it with a coefficient of zero before you start the division.
for example if you have x^3 - 3x + 12 you write it as
x^2 + 0x^2 - 3x + 12
The z-score of a certain data point in the given statistical data is calculated through the equation,
z-score = (x - m) / sd
where x is the data point, m is the mean and sd is the standard deviation.
Substituting the known values,
z-score = (51.8 - 52.3) / 1.8
z-score = -0.277
Rounding the answer to the nearest tenth will give an answer of -0.3.
The point (-5,6) is located in quadrant ll
B. Do you see how there is a pi symbol next to 308, that means you don't have to multiply by pi so 967.61 but divided by
Answer:
the answer is a+b
Step-by-step explanation:
7(3a-2b) +5(3b-4a)
21a-14b+15b-20a
