A submarine is 25m below the surface of the ocean. An airplane is flying 25m in the air above the ocean. Which statement below is NOT true? A. The submarine and the airplane's positions represent the same integer values. B. The submarine and the airplane are traveling at opposite integer values. C. The two distances represent equal absolute values. D. The two distances represent the same magnitude.

Its A

Step-by-step explanation: the submarine is below sea level therefore its in the negatives so they do no have the same integers values

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
