If both pairs of opposite sides are congruent, then the quadrilateral is a parallelogram. Given A(-5, 0), B (1, 5), C (5, 3) and D(-1, -2).

Find the lengths and determine is the quadrilateral is a parallelogram.

Find the value of 1715⋅211.though these numbers aren't quite as nice as the ones from the example or the previous part, the procedure is the same, so this is really no more difficult. give the numerator followed by the denominator, separated by a comma.

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
