Which pairs of polygons are congruent?
a pairs 1, 2 and 3
b. pairs 1.2.3, and 4
c. pairs 2 and 3
d. pairs 1 and 3

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!

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
