mn - 15 + 3m - 5n Rearranging: mn + 3m - 5n - 15 = m(n + 3) - 5(n + 3) = (m - 5)*(n + 3)

The GCF is n.

5n-5, because its the 5 time table (called 5n) minus 5 each time

That 5 is the cofficient of the term. The "n" is the variable!

mn - 4m - 5n + 20 = (mn - 5n) - (4m - 20) = n(m - 5) - 4(m - 5) = (m -5)(n - 4)

mn - 15 + 3m - 5n Rearranging: mn + 3m - 5n - 15 = m(n + 3) - 5(n + 3) = (m - 5)*(n + 3)

mn - 4m - 5n + 20 = m(n - 4) - 5(n - 4) = (n - 4)(m - 5)

The GCF is 5n

The GCF is n.

(m - 5)(n - 4)

(m - 5)(n - 4)

-5n - (-2) = 27 -5n + 2 = 27 -5n + 2 - 2 = 27 - 2 -5n = 25 -5n/-5 = 25/-5 n = -5

The GCF is MN.

5n-5, because its the 5 time table (called 5n) minus 5 each time

-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
