The first and third option.
Hope this helps.
Answer:
Step-by-step explanation:
has the form 
known as a difference of squares. It factors into (a+b)(a-b). To find a and b you take the square root.
The factored for is (a+b)(a-b).
In this case, it is
SSS is 3 sides, you already know EF and DW are identical and the two triangles share side DF, so you would need to know that ED ≅ WF
First, you must use ADDITION to find -12 + 8 (-4)
Then, use MULTIPLICATION to find -4*2 (16
1) Addition
2) Multiplication
