$\text{Hello there!}\\\\\text{Solve for x:}\\\\\frac{cx}{d}+f=b\\\\\text{Subtract f from both sides}\\\\\frac{cx}{d}=b-f\\\\\text{Multiply both sides by d}\\\\cx=d(b-f)\\\\cx=db-df\\\\\text{Divide both sides by c}\\\\x=\frac{db-df}{c}\\\\\boxed{x=\frac{db-df}{c}}$

The hypotenuse of the triangle is given by:
$CB ^ 2 = RC ^ 2 + RB ^ 2
$
Substituting values:
$CB ^ 2 = 2 ^ 2 + 4 ^ 2
$
Clearing CB we have:
$CB = \sqrt{ 2 ^ 2 + 4 ^ 2} 

 CB = \sqrt{ 4 + 16} 

 CB = \sqrt{20} 

 CB = \sqrt{4*5} 

 CB = 2\sqrt{5} 



$
Then, the perimeter of the triangle is:
$P = RB + RC + CB
$
Substituting values:
$P = 4 + 2 + 2 \sqrt{5} 

 P = 6 + 2 \sqrt{5}$
Answer:
the perimeter of triangle BRC in units is:
D.6 + 2√5
