(m - 5)(n - 4)
6m + 5n - 4m + 7n = 2m + 12n
It is simply: 5n+20 which is an algebraic expression because it has no equality sign
In the equation 5n-11=4n+20, n is equal to 31.
Previous poster was very wrong, 5n-3=17 5n=20 n=4
mn - 4m - 5n + 20 = (mn - 5n) - (4m - 20) = n(m - 5) - 4(m - 5) = (m -5)(n - 4)
(m - 5)(n - 4)
(m - 5)(n - 4)
a^2-a-20
6m + 5n - 4m + 7n = 2m + 12n
The GCF is 5n.
mn - 15 + 3m - 5n Rearranging: mn + 3m - 5n - 15 = m(n + 3) - 5(n + 3) = (m - 5)*(n + 3)
It is simply: 5n+20 which is an algebraic expression because it has no equality sign
(5n - 20) It's a binomial expression in 'n'. Its numerical value depends on the numerical value of 'n'.
In the equation 5n-11=4n+20, n is equal to 31.
