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

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

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
