What value of h makes the equation true -1/8 (2h+4) + 1/2 = -7/4 h= 7 25/16 7/16 25

Factor -8x3-2x2-12x-3 by grouping what is the resulting expression?

Negative 5 1/12 + negative 4 1/4 + 6 3/4

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.
