Answer:

first option

Step-by-step explanation:

To obtain ( f ○ g)(x) substitute x = g(x) into f(x) , that is

f(\frac{1}{2x} )

= \frac{2}{\frac{1}{2x}+3 } ( multiply numerator/ denominator by 2x to clear the fraction

= \frac{2(2x)}{2x(\frac{1}{2x}+3) }

= \frac{4x}{1+6x}

trapecia [35]
The perimeter of any shape is just what you get when you add up all of the side lengths. We know that one side is 462 meters, and since a square has four equal sides, we can just mulitply 462 × 4 to get our perimeter, 1,848 meters.

Sliva [168]

Answer:

Step-by-step explanation:

GIRL! You should add diagrams to these types of questions. It would really help

That 10cm does not mean point C is 10cm. It means the line AB is 10 cm in total.

And since point C is the midpoint, which means that point C cuts the line AB in half, that makes AC = 5cm
