The second answer

Step-by-step explanation:

We need to solve for r first. -2r ≥ 16; r ≤ -8. From this, we see that the sign is less than or equal to, which means the circle will be closed in. The answers to this inequality can be r = -9, r =-10, etc., which means that the second answer is correct.

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

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!
