Catie is trying to determine the height that a ladder reaches as it leans against a wall. She walks under the ladder and touches
brilliants [131]
18.56 feet
Catie creates a similar triangle with the ladder so we can create a proportion to solve for the height.  
\frac{baseto feet}{base to wall} = \frac{catie height}{wall height}
Convert all values to feet . 16in = 1.33 ft . 5ft 6 in = 5.5 ft 
Insert values into proportions
\frac{1.33}{4.5} = \frac{5.5}{x}
Cross multiply to get
24.75=1.33x
divide both sides by 1.33
x=18.56ft

9x^2-12x+4=0 

(3x)^2-2\cdot 2\cdot3x+2^2=0

(3x-2)^2=0, but...(3x-2)^2 \geq 0 , ∨ x∈R

So, (3x-2)^2=0

3x-2=0 ⇒ 3x=2 ⇒ \boxed { x= \frac{2}{3}  }
