Use mathematical reasoning to choose the expression that is greater than 12. A *x 16) x3 18-1 x 15) C (3-1) x (6 x 1) D 18 = (3x1)​

tube or goog would be a great resource to with that question

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.
