Solve each given equation & show your work. tell whether it has one solution (something like x=18), an infinite number of solutions (such as when any value can be used for x, and the equation is true), or no solution (no x value will work). (a) 6x + 4x - 6 = 24 + 9x

What is the upper quartile in the box plot?

Find the area of the regular hexagon if a side is 20 cm.

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.
