Answer: The probability of drawing a heart out of the deck is 13/52, or 1/4. The probability of drawing an even number as card #2 (c∈{2,4,6,8,10}) for any suit is 20/51, except when the first card drawn is an even heart, then the probability of the second draw is 19/51.

Answer:
In the Pythagorean Theorem, a right triangles hypotenuse is found by a^2 +b^2= c^2. The distance formula is basically the same thing. With two points, a right triangle can be formed and the slop would be the hypotenuse. That's where the distance formula comes from

Using the picture, we know (2x+6)+(5x-3)=24. Simplify to find x. 
7x+3=24
7x=21
x=3
We know AB=2x+6, and x=3. Plug 3 in for x.
AB=2(3)+6. 
AB=6+6
AB=12
