Answer:
solution set={18,10}
Step-by-step explanation:
x²-8x-180
comparing the above equation with the standard quadratic ax²+bx+c=0 equation,we get
here a=1 and b=-8 and c=-180
the quadratic formula is
x=-b±√(b)²-4ac/2a
putting values in the quadratic equation
x=-(-8)±√(-8)²-4(1)(-180)/2(1)
x=8±√64+720/2
x=8±√784/2
either
x=8+√784/2 or x=8-√784/2
x=8+28/2 or x=8-28/2
x=36/2 or x=-20/2
x=18 or x=-10
solution set = {18,-10}
i hope it will help you

Answer:
2 out of 5
Step-by-step explanation:
I believe that 96/240 needs to be simplified until it cant anymore, an that is the probability because they both fit three, I will divide by three.
96/3=32
240/3= 80
<u>32/80</u>
2
16/40 then because they both fit four, Ill do four.
4/10then 2 again
2/5 so, it is 2 out of five
please correct me if I am wrong, I was never good at probabilities, but I am better now.
