Well, to solve, garph the equation y=x^2+2x-8 and y=0
see where they intersect
anyway the easier way is to factor but anyway
0=(x-4)(x+2)
anyway
solution is x=4 and -2
A and D are answers (they are same)
They can show change on how much time passed.
There are multiple answers, you would need to know some of the other variables. Just do this. 70 - ( y * b) = r
Answer:
100%
Step-by-step explanation:
There is no table, but if there is only a green or red in the bag, then the probability of selecting a green or a red is 100%.
They would be alternate exterior so they would have to to be equal
2k + 11 = 131
-11 -11
2k = 120

2k 2k
k = 60
