A rectangular park has an area of 64 square yards. If we multiply its
length and width by 12, what will be the area of the new rectangle?
O A) 1642 yd?
OB) 9216 yd?
OC) 12,712 yd?
OD 170,048 yd?

Mary had at least an 80% on her test write an inequality to represent this situation

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.
