Which expression is equivalent to -3(2m-1)-m

Hey there!

••In order to solve this problem you can use the "distributive property" ••

So,

• -3(2m) = -6m

• -3(-1) = 3

•••• Problem becomes: -6m + 3 + -m ••••

•• Combine your "like terms" ••

• -6m & -m

• -m = -1m

• 3 & 3

Problem becomes: (-6m + -1m ) + 3

-6m + -1m = -7m

-7m + 3

Good luck on your assignment and enjoy your day
