Which is the correct data set for the box-and-whisker plot shown above? A. 8, 10, 1, 6, 9,7,5, 3, 2,2
B. 8,3,3, 4, 6, 2, 1, 10, 6,2
C. 1, 5, 6, 3, 7, 5, 2, 3,9,7
D. None of the above
Can anyone explain how to do this?

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

i'm not really sure how to answer that
