Answer:
1. False 2. True
Step-by-step explanation:
For a geometric sequence,
1. The sequence is :
3, 13, 23, 33,...
It is not geometric. It is false
2. The sequence is :
5, -25, 125, -625
So, the sequence is geometric as the common ratio is same. It is true.
Answer: The change received is $8.00
Step-by-step explanation:
20-12=8
3a^2 - 14(a) - 24
3a^2 + (-18a+4a) - 24
3a^2 - 18a + 4a - 24
(3a^2-18a) + (4a - 24)
3a (a - 6) + 4 (a - 6)
Answer is (a -6) (3a + 4)
