Sorry I need to answer something so I can ask questions so I’m typing this
4 P 4 = 24
4 P 4 = 4! (4-4)! = 4!/1 = 4*3*2*1
you are doing combinatorics, yes?
The way the question is worded is a little confusing.
I think I would say 10m. It could be 5m, but usually they list length first, then width. The perimeter, the whole distance around the outside, is 30 m (10 + 10 + 5 +5)
Answer:
x² -2x +4
Step-by-step explanation:
You recognize the dividend as the sum of two cubes. The factorization of that is ...
... a³ + b³ = (a + b)(a² -ab +b²)
In your problem, you have a=x, b =2, so the factorization is ...
... (x³ +8) = (x +2)(x² -2x +4)
When this is divided by (x +2), the result is (x² -2x +4).

You can also use long division or synthetic division to get the same result.
