Select all that are terms of the algebraic expression 4a2b - 16ab2 + 32a2b2.
a. 16a
b. 4a^2b
c. -16ab^2
d. 4ab
e. 32a^2b^2
f. 32

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.
