If P equals p plus at Find a when P equals 82 p equals 76 and t equals 20?
P = p + at 82 = 76 + a*20 6 = a*20 6/20 = a that is a = 3/10 or 0.3 That is the answer.

A student opens a mathematics book to two facing pages. The product of the pages numbers is 420. Find the page numbers?
If one of the pages is numbered p, the other is p+1. So p*(p+1) = 420 That is, p2 + p - 420 = 0 which factorises as (p - 20)*(p + 21) = 0 That implies that p = 20 or p = -21. Assuming that pages do not have negative numbers, p = 20 and then the other page is p+1 = 21.
If the length of a room is 20 feet and its width is 12 feet the perimeter of the floor area is?
p=2(L)+2(w) p=(2*20)+(2*12) p=40+24 p=64
