A and D
They don't have the same length measurements (congruent) nor are they the same size due to the due to the difference in angle and length measurements.
Answer:
(2^-6)*(2^3)
=2^(-6+3)
=2^-3
=1/(2^3)
=1/8
nth term = 7n - 2
Step-by-step explanation:
a = first term = 5
d = common difference = second term - first term
= 12 - 5 =7
d = 7
a + (n-1)d
= 5 + (n -1)7
= 5 + 7n - 7 {add like terms}
= 7n - 2
