Rearrange the formula s = a (a - r) forr. a) r = a(s - 1) b) r = (s - 1) a c) r = a(s - 1) s d) r = a(s + 1) s

C)

Step-by-step explanation:

The given formula :

To rearrange the formula to find the formula for r , first we multiply both sides with (a-r), we get

Divide both sides by S , we get

Subtract a on both sides , we get

Multiplying (-1) on both sides , we get

Hence, the correct answer is : C)
