Please try to explain the answer.
Which of the following functions is equivalent to the function below?

Select two that apply. f(x) = 3^(2x+1)

g(x )= 3 ⋅ 9^x

g(x )= 3^(2x) + 3

g(x )= 27^x

g(x) = 2 ⋅ 3^(x) + 1

g(x )= (1/3)^(−(2x+1))

g(x) = 9^(x) + 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.
