= 2m - 9n - 6m + 3n - n
combine like terms (m with m terms and n with n terms)
= (2m - 6m) + (-9n + 3n - n)
add/subtract in parentheses
= -4m - 7n
ANSWER: -4m - 7n is the simplified expression
Hope this helps! :)
The width can be x.
so it means that the length is 2x
the equation would be
2(x+2x)=24 inches
2x+4x= 24
6x= 24
x=4 (this is the width, so the length will be 8 inches)
the area will be 4 times 8 = 32
I dont know. So i am sorry ask someone alse. Thanks
First you go to -8 on the y intersept, next you go up 1 and move 1 to the right
Option C would be the correct answer :)
