Polygon ABCD = polygon EFGH which of the following is not true

D.

Step-by-step explanation:

When looking at polygons such as these, you have to look at the line the answer addresses and see if it corresponds to the same line with the other polygon. Letter D says that line BC is congruent to line GH, but line BC is shorter than line GH, which shows that they are not congruent.

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!
