### Subject: Physics (Heat Transfer)

Write the general energy balance equation for any given thermodynamic system

Qout - Qin + Wout - Win + £Mout(Hout + Vout^2/2 + gz) - £Min(Hin + Vin^2/2 + gz) = 0

### Subject: Geometry

Find the length of side c given the following measurements of a triangle: a = 2 B = 3.

In order to solve this equation you must use the pathagorean theorem and solve for c. A^2 + b^2 = c^2. Step 1: (2)^2 + (3)^2 = c^2 4 + 9 = 13 Step 2: c = square root of 13 C = 3.6

### Subject: Algebra

In algebra you will solve for unknown variables in a given equation, for example solve the following equation for x: 36 - 4x = 2

In order to solve for x, you need to follow the order of operations and get x by itself. Step 1: subtract 36 from both sides -4x = 34 Step 2: divide both sides by -4 X = 8.5
