PLS ANSWER ASAP which could be used to evaluate the expression -6 (4 2/3)
A. (-6)(4)+(-6)(2/3)
B. (-6)(4)x(-6)(2/3)
C. (-6+4)+(-6+2/3)
D. (-6+4)x(-6+2/3)

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.
