blagie [28]3 years ago
6 0

Answer:

B.

Step-by-step explanation:

If n = 1 ,  a1 = 9^1^2 +3 = 12

a2 = 9*2^2 + 3 = 39

a3 = 9*3^2 + 3 = 84

The differences are 39 - 12 = 27 and 84 - 39 = 45   so it is not arithmetic as an arithmetic series ad a common difference.

What is the value of v? 4/5(v−7)=2
Nostrana [21]
4/5(v - 7) = 2...distribute the 4/5 thru the parenthesis
4/5v - 28/5 = 2 ...multiply everything by 5
4v - 28 = 10...add 28 to both sides
4v = 10 + 28
4v = 38
v = 38/4 reduces to 19/2 or 9 1/2 <==
