<span> -(x + 1) - 5 > 10
-x - 1 - 5 > 10
- x - 6 > 10
Add 6 to the both sides,
-x - 6 + 6 > 10 + 6
-x > 16
x < -16 [ changed sign 'cause changed -sign ]
In short, Your Answer would be x < -16
Hope this helps!</span>

Answer: 31 - 3n
Step-by-step explanation:
step one:
25 - 28 = -3
22 - 25 = -3
19 - 22 = -3
d = -3
Step two:
An = a1 + (n-1) d
= 28 + (n-1) -3
= 28 - 3n + 3
= 31 - 3n
a1= 28 d = 3
Perimeter: You have to add up ALL the sides 12+12+3+3= 30 in square is the Perimeter
Area: Multiply l*w A=l*w, so 12*3= 36 36 in. square is your Area
