Given : -(3x+y)+2(x-4y).
To find : which expression is the simplest form .
Solution : We have given
-(3x+y)+2(x-4y).
Remove parenthesis

Dimensions of the hallway mural:
L = x + 6, W = x - 2.
An expression is:
A ( hallway mural ) = ( x + 6 ) · ( x - 2 )
If x = 8 ft ( length of each side of the classroom ):
A ( h. m . ) = ( 8 + 6 ) · ( 8 - 2 ) =
= 14 · 6 = 84 ft²
The area of the hallway mural is 84 ft².
