where the expression is defined?

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

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.
