h²=p²+b²

20²=x²+12²

400-144=x²

256=x²

16²=x²

square will be cancelled so answer is 16

h²+b²=H²

x²+12²=20²

x²=20²-12²

x²=400-144

x²=256

look for the square root,,,which is 16

and so x=16

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!

no i do not : ( what is it?
