3m
9m + 9m + 3m + 3m = 24m
-3m + 8 - 7 = -3m + 1
5m+3=3m+9 5m+3-3=3m+9-3 5m=3m+6 5m-3m=3m+6-3m 2m=6 (2m)/2=6/2 m=3
3m*3m*2m=300*300*200=18,000,000cm3
3m is 3000mm.
They are equal. 1m = 100cm 3m = 300cm
4 + 3m is already in its simplest form.
It is 9m^2 - 9 = (3m + 3)*(3m - 3).
-3m + 8 = 2 -3m = 2 - 8 -3m = -6 m = -6/-3 m = 2
