What is the answer for 4039 divided by 9

What is the area of mnp? 40 m2 60 m2 68 m2 127.5 m2

Which shows one way to determine the factors of 4x3 + x2 – 8x – 2 by grouping?

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.
