Need points, don’t use this
Answer is A
Please take the time to type in the question by yourself. I assume you use some kind of an apps to transcribe problems. It only confuses and discourages helpers. The fact that the question was reported means it is not clear.
I ASSUME the question is as follows:


Need to find P-G.
We see clearly that each expression P, G contains 3 terms, namely w^4, w^2z^2 and z^4. We will have to add/subtract like terms to get the answer.


(distribute negative sign into expression G)

(group like terms)

(add/subtract like terms)
It should be AAS because the angles overlap and the sides overlap because the triangles are congruent
Are you looking for the word SUM because that is an answer to an addition problem
