Explanation

To evaluate the expression (3 - 2) + 2(-2 4); (-75); (3 - 1), we can perform the necessary calculations.First, let's simplify the expression (3 - 2) + 2(-2 4):(3 - 2) + 2(-2 4) = 1 + 2(-2 4) = 1 + (-4 8) = 1 + (-4, 8) = (1 - 4, 1 * 8) = (-3, 8)Next, let's evaluate the expression (-75):(-75) = -75Finally, let's evaluate the expression (3 - 1):(3 - 1) = 2Therefore, the evaluated expressions are:(3 - 2) + 2(-2 4) = (-3, 8)(-75) = -75(3 - 1) = 2
