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 make v the subject of the formula.
In the formula F = 9/5 C + 32 , find c when f = 68.
60
20
30
40
A number decreased by 15 is 35.Derive the formula
x - 15 = 35
15 - x = 35
35 - 15 = x
x -35 = 15
The rule that the Perimeter (P ) if a rectangle is thrice the sum of its length (l ) and breadth (b ) is given by the formula _______.
P = 2 (l b )
P = ( l + b )
P = 3( l + b )
None of these
Frame a formula for " perimeter (p) is twice the sum of its length (l) and breadth (b)
P = 2l + b
P = l + 2b
P = (l + b)2
P = 2(l + b)
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
