What is the answer when you evaluate 8p5?

 6720

Step-by-step explanation:

The number of permutations of n things taken r at a time is given by the following formula:

Similarly, for n=8 and r=5, the number of permutations of 8 things taken 5 at a time will be:

Hence,

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
