Answer:

Step-by-step explanation:
We can use the pascal triangle to find the coefficients of the expasion of the cube. It holds that

Basically the real one is 80 times the picture
80 times 3/4=80/1 times 3/4=240/4=60in=5ft
it is 5ft long or 60in
We have 1 green and 8 non-green.
We get a probability of 8/9 of a non-green for the first marble and a probably of 7/8 for the second being non green, so
p = (8/9)*(7/8) = 7/9
Answer: 7/9
Represents the line graphed
Plugging in x=-2, you get:
2(-2)^2+5(-2)=2*4-10= -2
Therefore, f(-2)= -2
