Segment KJ shown below is the hypotenuse of isosceles right triangle JLK.

On a coordinate plane, triangle J L K has points (2, 4), (5, 1), (2, negative 2).

What is the length of one of the congruent legs of JLK?

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.

answer is (b.

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
