Answer:
A
Step-by-step explanation:
regular distance formula is
D= square root (x2 - x1)^2 + (y2-y1)^2
1 is false, 2 is true, and 3 may be false because the corresponding angles have to be equal and the corresponding sides be proportional. So I don’t know about 3 but 1 and 2 I’m sure of
Answer:

Step-by-step explanation:
Answer:
f(9)=-22-9(9)+20=-83
