Let p (n) be the statement that a postage of n cents can be formed using just 4-cent stamps and 7-cent stamps. the parts of this exercise outline a strong induction proof that p (n) is true for n ≥ 18. a) show statements p (18), p (19), p (20), and p (21) are true, completing the basis step of the proof. b) what is the inductive hypothesis of the proof? c) what do you need to prove in the inductive step? d) complete the inductive step for k ≥ 21. e) explain why these steps show that this statement is true whenever n ≥ 18.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

answer: 30

step-by-step explanation: its 30 because im a basketball player and stephen curry hits most of his shots so if you put 30 you might make the shot goodluck
