Can someone help me with this algebra question please 100% correct only

The answer is:  [D]:  " 24 + 2w " .
___________________________________________
Explanation:
___________________________________________
Given: The formula for the Perimeter of a rectangle:
___________________________________________
   P = 2L + 2w ; 
  
                 in which:
                                P = perimeter ;
                                L = length = 12 units (given); 
                                w = width = unknown;
_______________________________________________________
           Find the perimeter, "P", in terms of "w" ; since "w" (width) is unknown; and considering the answer choices given; along with the information provided in the problem, we only have enough information to solve for the perimeter, "P", in terms of "w" ; 
_____________________________________________________
         So, given the formula/equation for the perimeter, "P" :
_____________________________________________________
       P = 2L + 2w ;  we know that:  " L = 12 units " ;
_____________________________________________________
       P = 2*12  +  2w  =  24 + 2w ;  which is:  "Answer choice: [D]" .

Lines AB and CD are parallel. The coordinates of point A are (-2,5), the coordinates of point B are (6,3), and the coordinates o
adoni [48]

Equation of the line CD is equals to y = \frac{-x}{4} +7.

<h3>What are parallel lines?</h3>

" Parallel lines are defined as the lines in the same plane never intersect with each other. They are equidistant to each other in the same plane."

Formula used

Slope = \frac{y_{2} -y_{1} }{x_{2}-x_{1}  }

According to the question,

Given,

Coordinates of A (x_{1},y_{1}) = ( -2 , 5)

Coordinates of B (x_{2},y_{2}) = ( 6 , 3)

Substitute the value to get the slope of line AB we get,

Slope of line AB  'm_{1}' =\frac{3-5}{6-(-2)}

                    ⇒ m_{1} = \frac{-2}{8}          

                              = \frac{-1}{4}

Coordinates of C (x_{1},y_{1}) = ( x ,y)

Coordinates of B (x_{2},y_{2}) = ( 8,5)

Substitute the value to get the slope of line CD we get,

Slope of line CD  'm_{2}' =\frac{5-y}{8-x}

Lines AB and CD are parallel.

Slope of parallel lines are equal.

Therefore,

                     m_{2} = m_{1}          

                 ⇒ \frac{5-y}{8-x} = \frac{-1}{4}

                ⇒5-y = \frac{-1}{4} (8-x)

                ⇒ y = \frac{-x}{4} +7

Hence, equation of the line CD is equals to y = \frac{-x}{4} +7.
