Answer:
The expression that represents the perimeter of the rectangle is "12*x + 18", where "x" is the length of the rectangle.
Step-by-step explanation:
In order to solve this question we were given an expression that relates both dimensions of the rectangle. This expression in a mathematical form where "x" is the length and "y" is the width is shown bellow:
y = 9 + 5*x
The perimeter of a rectangle is given by:
perimeter = 2*length + 2*width
perimeter = 2*x + 2*(9+5*x)
perimeter = 2*x + 18 + 10*x
perimeter = 12*x + 18
The expression that represents the perimeter of the rectangle is "12*x + 18", where "x" is the length of the rectangle.

Answer:
Its B. two
Step-by-step explanation:
9·2 =18 and 18-2 =16
Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :
here x₁ = 2 and x₂ = 0 and y₁ = 0 and y₂ = 3
⇒ Slope of the line k is 
We know that : If two lines are perpendicular, then the product of slopes of the two lines should be equal to -1
⇒ Slope of line k × Slope of line perpendicular to k = -1
⇒ 
⇒ Slope of line perpendicular to line = 
Option C is the Answer
