(a + b)(b - 2c)
This is known as the Cosine Rule.
(a+b-c)2 = a2 + b2 +c2 +2ab - 2bc - 2ac
The expression ( (A - b + C)^2 ) can be expanded using the formula for the square of a binomial, which states that ( (x + y)^2 = x^2 + 2xy + y^2 ). In this case, it expands to ( (A - b + C)(A - b + C) ), resulting in ( A^2 - 2Ab + 2AC + b^2 - 2bC + C^2 ). Thus, the value of ( (A - b + C)^2 ) is ( A^2 + b^2 + C^2 - 2Ab + 2AC - 2bC ).
well finding the surface area of one face is just like finding the area of a flat rectangle, so all you have to do is find the area of each face and add them up into one sum. i believe that the formula is 2ab + 2bc + 2ac
ab-2ac+b^2-2bc
2ac
2a(2b-c) :P
2ac Ft. Dr Dre
AC, 2AC, 3AC, 4AC, 5AC and so on.
Surface area = 2ab + 2bc + 2ac
(a + b)(b - 2c)
(a + b)(b - 2c)
3ac + 2ca = 3ac + 2ac = (3 + 2)(ac) = 5ac
(2a + c)(4a2 - 2ac + c2)
