A. 2 distinct roots.
2x^2 + 8x + 3 = 0
Finding the discriminant:
b^2 - 4ac = 8^2 - 4 * 2 * 3
= 64 - 24
= 40
The discriminant is positive but not a perfect square
So there are 2 distinct ,real, irrational roots.
960
Multiply 8x12x10 and you get 960
(g+b)*8
first add all of the people
and then multiply that by 8
A = (-4,2)
A' = (-2,-3)
A'' = (3,1)
