How many ways are there to walk in xy space from the point (0,0) to (2,3) in exactly 5 steps if in each step, you walk 1 unit along the x or y axis only going in the positive direction?

Therefore there are 10 ways to walk in xy space from (0,0) to (2,3).

Step-by-step explanation:

To move from (0,0) to (2,3) one has to walk 2 step along x-axis and 3 steps along y-axis.

One can chose 2 steps along x-axis and then 3 steps along y axis

Or,

2 steps along y-axis ,1 step along x-axis , 1 step along y-axis,1 step along x-axis

And so on.

This is a permutation of(2+3) things where 2 and 3 are two types of kinds.

The required permutation is    

Therefore there are 10 ways to walk in xy space from (0,0) to (2,3).

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
