5n - 4 = 10n + 6-5n = 10n = -2
5n+6=-45n=-10n=-2

20n2+6n-2 (4n + 2)(5n -1) This problem can be solved by FOILing. First, multiply the first terms to get 20n2 Next, multiply the outside terms to get -4n. Multiplication of the inside terms results in 10n. Combining -4n and 10n (they are like terms) is 6n. Then, multiply the last terms, to get -2. Combining these answers into one equation gives the answer of 20n2+6n-2.
5n+4=0 5n=-4 n= -4/5
If the 10N force is positive, meaning to the north, then the 5N south would be negative, and the net force is 10N + (-5N) = 5N to the north.
5n - 4 = 10n + 6-5n = 10n = -2
5n+6=-45n=-10n=-2

5n+2 or 5n-2. I'll assume 10n 10,20,30,40,50
A resultant force of 15N cannot be produced by two forces of 10N and 5N. The possible resultants of these forces are 5N (when the forces are in opposite directions) and 15N (when the forces are in the same direction).
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
The net force is 2N north. This is because when you subtract the 5N force south from the 7N force north, you get a resultant force of 2N north.
5m-5n+5m+5n When simplified: 10m
3n+5n=8n
6n + 5n is 11n.
