Accepted Solution

A:

Answer:-4.2 - 0.72x (second)-0.72x + (-4.2) (third) -4(0.18x + 1.05) (fifth)0.6(-7) + 0.6(-1.2x) (seventh) Step-by-step explanation:okay so 0.6(-7 - 1.2x) = -4.2 - 0.72x or -0.72x - 4.2 or -4.2 + (-0.72x) or -0.72x + (-4.2) they are all the same meaning these are all the simplified answers so the first one is incorrect because it is -4.2 - 1.2x (simplified) the second one is correct because it is -4.2 - 0.72x (simplified) the third one is correct because it is -0.72x - 4.2 (simplified) the fourth one is incorrect because it is -4.2 + 0.72x (simplified) the fifth one is correct because it is -0.72x - 4.2 (simplified) the sixth one is incorrect because it is -4.2 + 0.72x (simplified) the seventh one is correct because it is -4.2 - 0.72x (simplified)
