Two identical number cubes are shown in the picture. The edge length of these number cubes is 3 centimeters. 10 What is the combined volume on the two number cubes in cubic centimeters? A 54 cm B 18 cm C 9cm D 27 cm​

In the figure shown below, m < 40 and ab =8. which equation could be used to find x?

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.

How can (square root of 25) ^2 be rewritten?
