Mariah started to find the solutions of x2 + 4x + 1 = 0. her work is shown below. x2 + 4x + 1 = 0 x2 + 4x = β1 x2 + 4x + 4 = β1 + 4 (x + 2)2 = 3 which describes the solutions of the equation?
since -2 and 3 are both rational, the sum and difference are both rational
since -2 and /3 are both rational, the sum and difference are both rational
since -2 is rational and /3 is irrational, the sum and difference are irrational.
since /2 is rational and /3 is irrational, the sum and difference are irrational.

Ascientist wants to use a model to present the results of his detailed scientific investigation. why would a model be useful? a )because the model makes the concepts easier to understand b) because the model is easy to put together and to use c) because the model prevents other scientists from asking questions d) because the model requires the audience to pay full attention to it i don't know what to choose because between a and d a is much more likely than d because it only wants to get the attention of the audience. i'm confuse.
