-5n - (-2) = 27 -5n + 2 = 27 -5n + 2 - 2 = 27 - 2 -5n = 25 -5n/-5 = 25/-5 n = -5
It is when factored: (N-8)(N+3)
-5n+9=-46 -5n+9-9=-46-9 -5n=-55 -5n/-5=-55/-5 n=11
5n+4=0 5n=-4 n= -4/5
5n + 7 = -41 5n = -48 n = -48/5 n = -9.6
The GCF is 5n.
It is: 2n^2 -5n -42 equals (2n+7)(n-6) when factored
-5n - (-2) = 27 -5n + 2 = 27 -5n + 2 - 2 = 27 - 2 -5n = 25 -5n/-5 = 25/-5 n = -5
-48
5n-5, because its the 5 time table (called 5n) minus 5 each time
It is when factored: (N-8)(N+3)
-5n+9=-46 -5n+9-9=-46-9 -5n=-55 -5n/-5=-55/-5 n=11
5n - 10 = 0 5n - 10 (+10) = 0 (+10) 5n (/5) = 10 (/5) n = 2
That 5 is the cofficient of the term. The "n" is the variable!
5n+4=0 5n=-4 n= -4/5
9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
9-5n+1 = 15 -5n = 15-9-1 -5n = 5 Divide both sides of the equation by -5 to find the value of n: n = -5
