The temperature on mars ranges widely from -207 f to 80 f find the average of the temperature extremes on mars

.

Step-by-step explanation:

We have been given that the temperature on mars ranges widely from -207 f to 80 f. We are asked to find the average of the temperature extremes on mars.

To find the average of the temperature extremes on mars, we will divide the sum of both temperatures by 2 as:

Therefore, the average of the temperature extremes on mars is .

555.99.

step-by-step explanation:

hope this

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
