In that context, p stands for pence. There are 100 pence in the British pound.
If you mean: p^2 +14p +48 then it is (p+6)(p+8) when factored
14p
14p + 14q + p - 7q - 6p = 9p + 7q
10p + 5p - p = 15p - p = 14p
(p=-15)(p=1)
It is: 14/480 times 100 = 2.916% recurring 6
So 3p = 12, ie p = 4
Assuming you mean 7 multiplied by just 2p and assuming that p is a variable then p is calculated by: (7 * 2p) + 3 - 8 = 6p + 29 14p - 5 = 6p + 29 14p - 6p = 29 + 5 8p = 34 p = 4.25
20% of 70p = 14p = 20% * 70p = 20%/100% * 70p = 14p
6nx + 7p - 14p + 2nx + 6x = 8nx - 7p + 6x
70p
