Hallie wrote the expression 21m - 18n. McKenzie wrote an expression equivalent to Hallie's. Which expression could McKenzie have written?
Let's just factor 21m - 18n .....the common factor is 3...so we have......
3(7m - 6n)
Use the distributive law:
3(7m - 6n) = 3(7m) - 3(6n) = <--- finish this
2(6m - 9n) = 2(6m) - 2(9n) = <--- finish this
3(7m - 4n) = 3(7m) - 3(4n) = <--- finish this
12(2m - n) = 12(2m) - 12(n) = <--- finish this
Can you finish these?
no i cant :P
