I got 21m+9 but it wasn't an option, can someone show me where I went wrong?
OpenStudy (cj49):
1/3(21m+27) 21m/3+27/3 7m+9
OpenStudy (bookworm14):
why would you put them both over 3?
OpenStudy (cj49):
bc the whole equation is multiplied by 1/3 eg 2/3(2m+3)=2/3 x 2m and 2/3 x 3
OpenStudy (bookworm14):
oh so you kinda use the distributive property ?
