Answer:

The length of the sailboat is 80 feet.

Step-by-step explanation:

The function  

s(l) = 1.34 \sqrt{l} ................ (1)  

models the maximum speed s in knots for a sailboat with length l in feet at the waterline.

So, using this model we have to find the length of a sailboat with a maximum speed of 12 knots.

Now, from equation (1) we get

12 = 1.34 \sqrt{l}

⇒ \sqrt{l} = 8.955

⇒ l = (8.955)^{2}  = 80 feet (Answer)

{The value is round to the nearest foot}

X^2+5x+6=0

or,x^2+(2+3)x+6=0

or,x^2+2x+3x+6=0

or,x(x+2)+3(x+2)=0

or,(x+3) (x+2)=0

Either,

x+3=0 x+2=0

or,x=-3 or,x=-2

Therefore,the value if x is -2 or -3 .
