PLEASE HELP ASAPPPPPP

1.It should have been:
x – 5 > 12
Add 12 on both sides of the inequality:
x – 5 + 5 > 12 + 5
x > 1

2.3 < x + 2

Switch sides:
x + 2 < 3
Subtract 2 on both sides of the inequality to isolate x:
x + 2 – 2 < 3 – 2
x < 1

Please see the attached image for the graphing of the solutions on the number line.

Equilateral, isosceles, and scalene are the type of triangles that can be formed by taking the cross section of a cube.

Hope this helps!!
