Remove parentheses
3m - 7m+12 = 2 m-3
collect like terms
3m-7m-12 = 2m-6
move terms
-4m - 12 = 2m-6
collect the like terms and calculate
-4m-2m = -6+12
divide both sides by -6
-6m=6
m= -1
The answers would be E,C,B. Hope this helped out it might not be right but trying my best to help out.

Answer:
lol, hello again!
SA = 456 cm²
Step-by-step explanation:
small rectangle SA: 6*4 + 6*8 + 6*4 + 6*8 + 4*8 = 176
large rectangle SA: 2*14 + 2*8 + 2*14 + 2*8 + 8*14 + (8*14 - 8*4) = 280
Total SA = 176 + 280 = 456
I'm guessing the answer is 6in.
because the original width of the photo is 8in-4in
which is 4in.
and 8 to 10 is a difference of 2
so add 2 to 4
its 6
