Given the two sets: a = {1, 2, 3}
b = {3, 2, 1}

which of the following is a true statement?

Give all possible names for each angle shown.calculation tip: in angle abc, b is the vertex.

[15 points]find the least common multiple of the expressions: 1. 3x^2, 6x - 18 2. 5x, 5x(x +2) 3. x^2 - 9, x + 3 4. x^2 - 3x - 10, x + 2 explain if possible

Parabolas y=−2x^2 and y=2x^2 +k intersect at points a and b that are in the third and the fourth quadrants respectively. find k if length of the segment ab is 5.
