Prove that for all n e z, n is even iff n can be written in one of the forms 4k or 4k + 2 for integer k. (hint: for one of the directions, d 4) use the quotient-remainder theorem with some

i need the table so i can see

step-by-step explanation:

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.
