P(x)is a polynomial. P(-6) = 3 P(-4)= -1
P(4) = 2 P(6) = -5
What is the remainder when P(x) is divided by (x -- 6)?
What is the remainder when P(x) is divided by (x + 4)?

Determine the difference: 3.2 × 1010 – 1.1 × 1010. write your answer in scientific notation.

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.

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.
