12m + 3n - 6m + 7n6m + 10n
12m + 2n - 3m + 11n = 9m + 13n
m2 + 12m + 20 = ( m + 2)(m + 10)
12m + 9n - 4 - 10m + 6n = 2m + 15n - 4
(3+2) (4+48)

it would be 30mplus negative 7
Identify the law illustrated by: 12m + 0 is the same as 12m.
It is: 4(2x+3m) when factorised
1m = 100cm, therefore 12m = 1200cm. 12m is > 120 cm
150cm - 12m = 138
