mn - 4m - 5n + 20 = (mn - 5n) - (4m - 20) = n(m - 5) - 4(m - 5) = (m -5)(n - 4)
n = 70/5 n = 14
The GCF is 5n
40n^2 + 64n = n(40n + 64) = 8n(5n + 8)
The GCF of 10 and 40 is 10. 10 is a factor of 40, and 10 is the largest factor of itself, so 10 is the greatest common factor of 10 and 40.
5n - 10 = 0 5n - 10 (+10) = 0 (+10) 5n (/5) = 10 (/5) n = 2
5n-25 = 10 5n = 10+25 5n = 35 n = 7
5(n4m)
5n+15 = 25 5n = 25-15 5n = 10 n = 2
5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
-16
It is: 8n(5n+8)
5n + 10 = 10 5n = 10 - 10 5n = 0 n = 0 taylor101119: well i thought it was 5*n+5*2=10 i thought n=1 but i'm pretty sure it's the one ontop^
mn - 4m - 5n + 20 = (mn - 5n) - (4m - 20) = n(m - 5) - 4(m - 5) = (m -5)(n - 4)
9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
5n-5, because its the 5 time table (called 5n) minus 5 each time
(m - 5)(n - 4)
