Amir evaluated 5x - (x + 3)2 for x = 2, as shown. Describe Amir's mistake and find the correct answer. 5(2) - (2 + 3)2 = 10 + (-5)2 = 10 + 25 = 35

Answer:

By the order of operations, Amir should have squared 5 and then subtracted rather than distributing the negative and squaring. 5(2) - (2 + 3)2 = 10 - (5)2 = 10 - 25 = -15 Check all of the facts that you included in your response.Amir did not follow the order of operations.Exponents should be evaluated before subtracting.The correct answer is -15.
