Answer:
12.5%
Step-by-step explanation:
I warn you, I'm not positive I'm correct.
First I added 8+10+6 and got 24
I divided that by 3 and got 8
I divided 100 by 8 because if you cross multiply 1/8 and x/100 you would get 8x = 100
100 ÷ 8 = 12.5
So I got 12.5%
The quadratic formula is -b plus minus the square root of b^2-4ac all over 2a.
Here, a=1, b=13, and c=30.
The only option that fills in the values correctly is D
