Look at the student work shown below. simplify: 4t(2s – 7). (4t)(2s) – 7 8st - 7 did the student correctly simplify the expression? if “yes,” explain the steps the student followed. if “no,” explain what the student did wrong and what should have been done.

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.
