Bullentin board is 4 feet long and 6 feet wide..how many feet of border does it need to surround the bulletin board

To surround it? So In other words, you are looking at the perimeter

Width= 6 feet

Length= 4 feet

So you multiply because there are two two even sides

4×6=24

Answer=24 feet 

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the value of x is equal to 0.
