Answer:
1<x≤3
Step-by-step explanation:
An edge or a corner of the shape joins them but the vertex idk
= 12 + (- 6)(n - 1 )
This is an arithmetic sequence with n th term
=
+ (n - 1)d
here d = - 6 - 0 = 0 - 6 = 6 - 12 = -6 and
= 12, hence
= 12 + (- 6)(n - 1)
use this formula to find the 30 th term
= 12 + (- 6 × 29) = 12 - 174 = - 162
8x - 5(x - 3) = 18
8x - 5x + 15 = 18
3x = 18 - 15
3x = 3
x = 3/3
x = 1
