# A + 2b = c

Let c be chosen to be the longest of the three sides and a + b > c (otherwise there is no triangle according to the triangle inequality). The following statements apply: If a 2 + b 2 = c 2, then the triangle is right. If a 2 + b 2 > c 2, then the triangle is acute. If a 2 + b 2 < c 2, then the triangle is obtuse.

(a+b) 2 = a 2 + 2ab + b 2 (a+b)(c+d) = ac + ad + bc + bd a 2 - b 2 = (a+b)(a-b) (Difference of squares). a 3 b 3 = (a b)(a 2 ab + b 2) (Sum and Difference of Cubes Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history Jan 28, 2020 Jul 22, 2020 I was trying to prove the Heron's Formula myself. I came to the expression \$ 2(a^2 b^2+a^2c^2+b^2c^2)-(a^4+b^4+c^4) \$ ).

## Answer is 4 moles. A + 2B → C This means 1 mole of A reacts with 2 moles of B to produce 1 mole of C. Now you have taken 5 moles of A. So it will need 10

### Oct 04, 2008 · To counteract, we add a^2 bc - a^2c^2 + b^2 ca - b^2a^2 + c^2 ab - c^2 b^2 to the same side. The complete-square section is a^2(b - c)^2 + b^2(c - a)^2 + c^2(a - b)^2 and the added part is a^2 bc + b^2 ca + c^2 ab - a^2c^2 - b^2c^2 - c^2a^2. However, notice that the added part is EXACTLY the same as the equation (1). Apr 03, 2012 · a^3 + b^3 + c^3 - 3abc = (a + b + c)(a^2 + b^2 + c^2 - ab - ac - bc). By assumption a^3+b^3+c^3=3abc so the left hand side is 0. Therefore (a+b+c)(a^2+b^2+c^2-ab-ac-bc) = 0. So either a+b+c=0 or a^2+b^2+c^2-ab-ac-bc=0. Now suppose a^2+b^2+c^2 - ab-ac-bc =0. You can re-write this as: (1/2) ( (a-b)^2 + (b-c)^2 + (c-a)^2 )=0 Engineering ToolBox - SketchUp Extension - Online 3D modeling!

The roots are real and coincident if = 0.

All logical operators exist in C and C++ and can be overloaded in C++, albeit the overloading of the logical AND and logical OR is discouraged, because as overloaded operators they behave as ordinary function calls, which means that both of their operands are evaluated, so they lose their well-used and expected short-circuit evaluation property. a 2, b 2, and c 2 are the areas of the squares with sides a, b, and c, respectively; if γ is acute, then ab cos γ is the area of the parallelogram with sides a and b forming an angle of γ′ = π / 2 − γ; if γ is obtuse, and so cos γ is negative, then −ab cos γ is the area of the parallelogram with sides a and b forming an angle of History. The formula is credited to Heron (or Hero) of Alexandria, and a proof can be found in his book, Metrica, written c. CE 60.

### Hepatitis C, a virus that attacks the liver, is a tricky disease. Some people have it and may never know it as they are affected by any sorts of symptoms. It can remain silent until there is severe damage to your liver.

The following statements apply: If a 2 + b 2 = c 2, then the triangle is right. If a 2 + b 2 > c 2, then the triangle is acute. If a 2 + b 2 < c 2, then the triangle is obtuse. 2 a + 2 b + 2 c = 0.
