Which equation has the solution x = -4? 3x + 6 - 2x = -2
2(2 - 4) = 16
(x + 6) 3 = -6
-x +4=3

none of these have the solution of x = -4

Step-by-step explanation:

1 . 3x + 6 - 2x = -2 .    (combine like terms)

x + 6 = -2  (isolate the variable)

  -6     -6

x = -8    *x doesn't equal - 4*

2.  2(2 - 4) = 16    (distributive property)

2 - 8 = 16

-6 = 16

since theres no x in the equation its not a possible answer .

3 .  (x + 6) 3 = - 6  

this one also isn't a proper equation to find x

4.    -x + 4 = 3   (isolate the variable)

           -4    -4

-x = -1

/x .   /x

x= -1  

i need the options

step-by-step explanation:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
