Dimensions: x by 3x by x3 area of base = x(3x) = 3x2 box 2: dimensions: x by 4x – 1 by x3 area of base = x(4x – 1) = 4x2 – x complete the statements about the number of terms in the polynomial representing the volume of each box.

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.
