Answer:

5(2m+3)-4m is 3 less than 5(2m+3)-4m

Step-by-step explanation:

How does 5(2m+3)-4mcompare to 5(2m+3)-4m when m is a postive intenger .

Expand 2(3m+6) and 5(2m+3)-4m

2(3m+6)

= 2(3m)+2(6)

= 6m+12

5(2m+3)-4m

= 5(2m)+5(3)-4m

= 10m+15-4m

= 10m-4m+15

= 6m+15

Take their difference

6m+15 -(6m+12)

=6m-6m+15-12

= 3

THEREFORE 5(2m+3)-4m is 3 less than 5(2m+3)-4m
