C=25. S=a. B=4c-s2. What would b equal to

Answer: B = 100 - a^2

Solution:

Step 1: Substitute all the values that are given in the equation

that would be C = 25 and S = a

Step 2: when substituted the equation would be

B = 4 (25) - (a) ^2

B = 100 - a^2 Would be the answer

Note: if there was a numerical value to s then the answer would be a number but since s=a so the answer has variable too.
