Asquare has sides of x-.4.write an expression for the perimeter of that square. simplify the expression.

Your expression would end up being 4(x-4), which would simplify to 4x-16. Since a square has four equal sides, to find the perimeter you would just do the expression four times. Then you would apply the distributive property to find 4x-16. Hope this helps

3x - 8 = -2

3x -8+8 = -2 +8

3x = 6

3x/3 = 6/3

x = 2

s

x - 6

( 2-6)

= -4

that is the value of x -6

= -4
