125divided by p equals 25 = 5
p = -12

S is increased from 4 to 6: a multiple of 6/4 = 1.5 So P, which is directly proportional to S, increases from 18 to 18*1.5 = 27
3p+5+p = -23 3p+p = -23-5 4p = -28 p = -7
s = p^2 - 5 *also, p = sqrt (s+5)
If p = 2s + 5, then s = (p-5)/2 or 1/2 (p-5) --- p = 2s +5 p-5 = 2s (p-5)/2 = s
5 = sides of a pentagon(also 5 equals S of a SP means 5 = sides of a square pyramid)
The problem as stated does not allow for a solution for the value of S, however, the problem can at least be somewhat simplified. If m = p/5, then p + m can also be written as p + p/5, which simplifies to 1.2p so S = 1.2p

If P varies jointly as q, r and s - assume this is in direct proportion, then P ∝ qrs so P = kqrs where k is a constant.70 = k x 7 x 5 x 4 = 140k : k = 140/70 = 0.5When q = 2, r = 15 and s = 7 then,P = 0.5 x 2 x 15 x 7 = 105
If P varies directly with q, r and s then P = kqrs, where k is a constant. As 70 = k x 7 x 5 x 4 = 140k : k = 70/140 = 1/2 The equation of joint variation is P = ½qrs.
