Can you explain to me (detailed) on how to do this problem? I will give you a if you get this right.

To find the area of rectangles you have to multiply its height by its width. So, 12x2 equals 24. Therefore the area of the rectangle is 24km.

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!
