Which of the following correctly solves this equation? (-6)
O-6) (6) = 36
o(-6) (-2) = 12
.(-6) (-6) = 36
o(-6) (-6)= -36

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

is there answer choices?

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

you would need to also lose 1 point for each of the other outcomes for it to be fair.
