Pedro and Martha are hiking on a straight trail. They walk in the same direction at steady paces that are different from each other. They begin at the same time, but at different points. Martha crosses the 6-mile trail marker after 1 hour and crosses the 12-mile marker after 3 hours. Pedro's location over time is shown in the table. Time (hours) 1 3 5

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

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
