I think the answer is d. The slope of AC=Slope of DF.
Hope this helped☺☺
C. 10. you can calculate this by adding n to both sides to get 35=25+n and then subtracting 25 from each side to get n=10.
The answer would be D Because one side is 18 and another is 26 and 18 times 26 is 468.
17c because you have to pair the terms
