a^2 + b^2 + c^2 - ab - bc - ca = 0=> 2a^2 + 2b^2 + 2c^2 - 2ab - 2bc - 2ca = 0 => a^2 - 2ab + b^2 + b^2 - 2bc + c^2 + c^2 - 2ca + a^2 = 0 => (a - b)^2 + (b - c)^2 + (c - a)^2 = 0 Each term on the left hand side is a square and so it is non-negative. Since their sum is zero, each term must be zero. Therefore: a - b = 0 => a = b b - c = 0 => b = c.

The Big C - 2010 The Little c 2-6 is rated/received certificates of: Argentina:16 Netherlands:6
6 c - 4 c = 2 c, 7fl oz - 5 fl oz = 2 fl oz therefore the answer is 2 c 2 fl oz
Studio C - 2012 2-6 was released on: USA: 6 May 2013
It's a number that stays the same. Example: C is always 5. 6*C = 30. 10/C = 2 6-C = 1 2+C = 7. C is a constant.
If: 3c = 6Then: c = 2
7.8 because, the formula for a hypotenuse is a^2 + b^2 = c^2 the hypotenuse is "c" and the legs of the triangle are "a" and "b" 5^2 + 6^2 = c^2 5^2=25 6^2=36 so 25+36=c^2 25+36=61 so 61=c^2 square root each side and you get "c" equaling (to the nearest tenth) 7.8
If the points are (b, 2) and (6, c) then to satisfy the straight line equations it works out that b = -2 and c = 4 which means that the points are (-2, 2) and (6, 4)
Circumference is equal to 2(pi)r. So if C = 6, and 2(3.14)r = C, then solve for r r= 6/2(3.14) = .955
c2+6c+9 = (c+3)(c+3)
The Pythagorean theorem says; a^2 + b^2 = c^2 a = 6 b = 6 c = 10 6^2 + 8^2 = 100 could be a right triangle
