Answer:
x=-1
Step-by-step explanation:
2x - 3 = -4x - 9
Add 3 and 4x on both sides.
2x + 4x = -9+3
Add or subtract like terms.
6x = -6
Divide 6 into both sides.
6x/6=-6/6
x=-1
The solution to this equation is x=-1.

Step-by-step explanation:
The first application of the Pythagorean theorem is used to find the diagonal of one face. That is called 'a' in this problem. Then the second application of the Pythagorean theorem uses that value of 'a' along with the remaining prism dimension to find the space diagonal 'c'.

You don't actually have to find 'a', because you only need the value of a². Using the first equation to substitute into the second equation gives ...
6² +8² +12² = c²

Let's solve this inequality.
Let's isolate X. For this, the elements that are with it must be sent to both sides:
- 3 < - 4X + 1 < 13
- 3 - 1 < - 4X < 13 - 1
- 4 < - 4X < 12
<h2>- 3 < X < 1</h2>
<em>important: see annex</em>
Answer: x - 1.5
4x – 97 + 12 – x = -80.5
3 x - 85 = -80.5
3 x - 85 +85 = -80.5 + 85
3x = -80.5 + 85
3x = 4.5
x = 1.5
Step-by-step explanation: hope this helps
