For which equation(s) is -2 a solution? a.) 2x+6=2 b.) 2(x-4)=6x c.) 3x+1/2=1/4x+6 d. 3x+15=2x+9 plz someone i am really stuck

A and B.

Step-by-step explanation:

A.) 2x+6=2:

Move all terms that don't contain  x  to the right side and solve.  

x=−2

B.) 2(x-4)=6x:

Solve for  x  by simplifying both sides of the equation, then isolating the variable.

x=−2

C.) 3x+1/2=1/4x+6:

Solve for  x  by cross multiplying.

x=2

D. 3x+15=2x+9:

Solve for x  by simplifying both sides of the equation, then isolating the variable.

x=−6

answer: 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.
