I dont know the second part of the question but that's the answer I came up with

c

step-by-step explanation:

i think because what else can be a sample of every member

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.
