<h3>
Answer: -1 < x < 3</h3>
Work Shown:
| x-1 | < 2
-2 < x-1 < 2 ... see note1 below
-2+1 < x-1+1 < 2+1 ... see note2
-1 < x < 3
- Note1: use the rule that |x| < k turns into -k < x < k for some positive real number k.
- Note2: Add 1 to all sides to isolate x
Answer: 
Step-by-step explanation:
We can make the conversion from milimeters to meters (Remember that
). Then:
to
:

to
:

Now, we need to use this formula for calculate the area of a rectangle:

Where "l" is the lenght and "w" is the width.
Knowing that:

We can substitute values into the formula. Then we get:

A hexagonal prism should work! The two bases are hexagons, and there are 6 lateral faces that are rectangles. When you count the edges, there are 18... here's an image of one (just in case)
Answer:
28:20
Step-by-step explanation:
you just multiply 5 by 4 because 20 divided by 4 is 5 and then multiply 7 by 4
Answer:
31
Step-by-step explanation:
3x + 12 and 105 are alternate exterior angles because A || B and B || C.
If the two or more lines are parallel, then the alternate exterior angles are equal.
3x + 12 = 105
Substract 12 on both sides,
3x = 105 - 12
3x = 93
Divide 3 on both sides,
x = 93 / 3
x = 31
