they are letters in math like algerbra example AxA=b
Let's call the parallel sides A and B, and the distance between them as H. The area of the trapezium, or K, is (A+B)H/2. K = (A+B)H/2
I don't!
(b+h)(b+h)= b2+2hb+h2.
b/h
In the German note naming system, believe it or not, H major DOES exist, because what they call H we call B (natural) and what they call B we call B (flat).
H is what the Germans call the note B. B is what they call B-flat. That is why Bach could spell out his name in notes... Bflat-A-C-B.
A b***h

A and b are the variables cause they represent a number

Area of a parallelogram = b*h. Call the area of parallelogram one x and two y. We now know that x = y = b(x)h(X) = b(x)h(y). Now b(x)h(x) = b(x)h(y) b(x)h(x)/b(x) = b(x)h(y)/b(x) h(x) = h(y), so the height of the second parallelogram must equal the height of the first.
Use a temporary variable. Example (swap variables "a" and "b"): int a = 5; int b = 10; // Swap the variables int temp; temp = a; a = b; b = temp; System.out.println("a = " + a); System.out.println("b = " + b);Use a temporary variable.

Because there are only 7 notes. Actually in German music - the note which we call B is called "H" and the note Bb is called "B".
Actually, there is! German music uses letters A-H instead of A-G, it's not that there are different notes, it's just that the note they call B is actually a Bb, and H is the same as B natural.
H this is so Bach would be able to spell his names in his songs some still call it H.
