Is this expression a perfect square trinomial?

c. (3,2,6) is the answer.

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.

noncoplanar points are points that do not lie on the same line.

the correct answer is 1.7
