$x=+2\sqrt{10}$

$x=-2\sqrt{10}$

Step-by-step explanation:

40-x^2=0

To solve for x , subtract 40 from both sides

-40+40-x^2=0-40

-x^2=-40

Divide both sides by -1

x^2= 40

Take square root on both sides

$\sqrt{x^2} =\sqrt{40}$

$x=+-2\sqrt{10}$

The values of x are

$x=+2\sqrt{10}$

$x=-2\sqrt{10}$

Robin is winning the game and the explanation for the answer is :

Step-by-step explanation:

core represents the number of centimeter each player is away from the center. Given the mean of Robin = 107 and mean of Evelyn = 138

And, as it is mentioned that the player whose object lands more close to the center wins the game.

Evelyn has the greater mean. It indicates that, on average, Evelyn objects landed farther away from the center than Robin's.

Therefore, this difference means that Robin is winning the game.
