1 answer:
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
