A paper has an area of 78 square inches. What is the paper's area in square centimeters? Use the following conversion: 1 square inch is 6.5 square centimeters.

Which statement about perfect cubes is true

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.

If f(x) = 2x + 8 and g(x) = x4, what is (gº)?
