Answer:
<h2>
x = 19</h2><h2>
</h2>
Step-by-step explanation:
|<----------------- 71 ----------------------->|
E-----------------------F---------------------G
2x + 13 20
find: x
EF + FG = DG
2x + 13 + 20 = 71
2x = 71 - 20 - 13
x = 38 / 2
x = 19

1. ![\sf{(2x + 2) + (3 - 5x)}](https://tex.z-dn.net/?f=%20%5Csf%7B%282x%20%2B%202%29%20%2B%20%283%20-%205x%29%7D)
When there is a ( + ) in front of expression in parentheses , the expression remains the same.
⇒![\sf{2x + 2 + 3 - 5x}](https://tex.z-dn.net/?f=%20%5Csf%7B2x%20%2B%202%20%2B%203%20-%205x%7D)

Answer:
Arithmetic sequence
Step-by-step explanation:
A sequence is described as an arithmetic sequence when there is a common difference between the numbers
A sequence is a geometric sequence when there is a common ratio between the numbers
12,10,8
10-12= -2
8-10= -2
10/12= 0.83
8/10= 0.8
Hence the sequence is an arithmetic sequence with a common difference of -2
