Answer:
3
Step-by-step explanation:
All factorials 5 and above are evenly divisible by 15, so have no remainder. Thus, you are interested in ...
mod(1! +2! +3! +4!, 15) = mod(1 +2 +6 +24, 15)
= mod(33, 15) = 3
The remainder is 3.

Answer:
Step-by-step explanation:
-6 (-p + 8) = -6p + 12
distribute the -6 to the -p and the 8, so you now have 6p - 48 = -6p + 12
add 48 to both sides of the equation in order to isolate the x on one side. you now have 6p = -6p + 60
now add 6p to both sides to get all the "p's" on one side. equation is now 12p = 60
divide both sides by 12 to get p by itself and the answer is p = 5
