Prove that there exists a unique prime number of the form n2 – 1, where n is an integer that is greater than or equal to 2.

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(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.
