The zeroes ( where the graph cuts the x axis) ar (-2,0) AND (2,0)
tHE FACTOrIAL FORM IS (x - 2)(x + 2)
Its B
Angle A is 150
Angle B is 30
Supplementary= 180, so....
Angle A + Angle B = 180
150 + 30= 180
hope this helps
Answer:
The value is 
Step-by-step explanation:
From question we are told that
The number of types of marbles present jar is n = 3
Generally the probability of drawing a green marble is

Generally the probability of drawing a marble that is not green is

From the question we are told that there will be continuous drawing of marbles from the jar (in such a way that after each marble is drawn it is being replaced) until a green marble drawn
Let m be the number of times marbles has been drawn when a green marble was gotten
it then means that for m - 1 times the marbles where drawn a green marble was not obtain.
Generally the probability drawing m times is mathematically is mathematically represented as

=> 
Write an equation like this...
4 - 6x = 40
x = -6
Check:
4 - (6 x -6)
4 - (-36)
* A "-" symbol and "-" symbol equal a "+" sign
So...
4 + 36 = 40
Hope this helps! :3
