Answer:
= x − 4
Step-by-step explanation:
Let's simplify step-by-step.
3x−(2x+4)
Distribute the Negative Sign:
=3x+−1(2x+4)
=3x+−1(2x)+(−1)(4)
=3x+−2x+−4
Combine Like Terms:
=3x+−2x+−4
=(3x+−2x)+(−4)
= x - 4
The lowest number of strands usually seen is 7 ... one in the middle
and 6
surrounding it.
The next level up is 19, which is another layer of 12
strands on top
of the 7.
After that the number varies, but 37 and 49 are
common, then in
the 70 to 100 range (the number is no longer exact).
Even larger
numbers than that are typically found in very large
cables.
