Rita and Bernie both play the same online game. In today's play, Rita earns 6 points 3 times and loses 4 points twice. Bernie gets a bonus of 15 points for answering a trivia question correctly and then loses 25 points twice for giving wrong

answers. Choose ALL statements that correctly describe this situation.

Rita earns 10 points at the end of the play.

Bernie losses 35 points.

Step-by-step explanation:

Rita earns 6 points 3 time and loses 4 points twice

6 * 3 = 18

4 * 2 = 8

18 - 8 = 10 points

Bernie get bonus of 15 points

looses 25 points twice

15 -  (25 * 2) = -35 points

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
