c = 6 and d = 7
(a+d)/2b=c
C= pi * D This is the formula for circumference.

d = a - 2bc
c = 6 and d = 7
Without further information, all we can do is simplify: 4c + 4d = 4(c + d)
If: a = b+c+d Then: c = a-b-d
6d = c Divide both sides by 6: d = c/d
4C times D is the same as 4CD in algebra which means 4*D*C
c= (a+d) / 2b
(a+d)/2b=c
C= pi * D This is the formula for circumference.
Type your answer here... a = 2bc-d add d to both sides a + d = 2bc divide both sides by 2b (a+d)/2b = c
A = 2bc - dAdd 'd' to each side of the equation:A + d = 2bcDivide each side by 2b :(A + d)/2b = c

a + b = c a - b = d then a = (c + d)/2 and b = (c - d)/2 The fact that c and d are perfect squares is not relevant to solving a and b in terms of c and d. Furthermore, a complete solution of all four variables into unique numerical values is not possible.
