None of these
In s = d/t make t as the subject
t = d/s
t = s/d
t = sd
t = d2 s
In formula P = 2 (l x b ), make l the subject.
l = 2b - p/2
l = 2 -2b/p
l = p - 2/2b
l= p - 2b/2
Given s = d/t . find d when s = 36 and t = 5

Frame a formula for 1/5th of number x is 3 less than 20.
5x = 20 -3
5x = 3 - 20
x/5 = 20 - 3
x/5 = 3 - 20
Frame a formula " The product of 3 consecutive numbers ( the smallest being x is 310).
x × ( x + 1) × (x + 3) = 310
x × (x + 2) × (x + 4) = 310
x × (x + 1) × (x + 5) = 310
(x + 1) × (x + 3) × (x + 5) = 310
If A = π r2 find A when r = 14 cm and π = 22/7 ?
516 cm2
616 cm2
716 cm2
916 cm2

Frame a formula for " A number x multiplied by itself is 25 more than the number".
2x2 = 25
2x2 + x = 25
x2 = x + 25
x2 + 25 = x
Given v2 = u2 - 2ft,make t subject of the formula.
t = 2f (u2 - v2)
t = 2f (u2 + v2)
