Brie is training to run a 5K race. Today, her workout consists of walking of a lap, jogging Nine-tenths of a lap, and then sprinting Two-tenths of a lap. Finish the statement below using the drop-down menus. Brie jogged
of a lap farther than she walked, and she walked
of a lap farther than she sprinted.

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

idk what the heck he answer is, i’m just putting this here so i finish my account

he answer is x=1x3 because x=1 to x=3
