On a cold night in antarctica. the temperature dropped 0`c to -21c in 6 hours. what is the average temperature change per hour( give me the answer)

-3.5C

Step-by-step explanation:

(-21)-0=-21

First find the Difference in temperatures.

(-21)/6=-3.5

Then Divide by the amount of time passed.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
