Two sides of a triangle measure 8 meters and 12 meters. What is a possible side length for the third side?

I think it is C.

The triangle inequality states that the side of a missing side has to be greater than or equal to the other two sides when added.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
