Answer: 13.722 km ; or, write as: 13 13/18 km .
___________________________________________________
Explanation:
___________________________________________________
Area = Length * width ;
___________________________________________________
or, write as: A = L * w ;
________________________
Given: A = 247 km² ;
L = 18 km ;
w = "y" ;
________________________
Find: "y"
______________________________
A = L * w ;
______________________________
Plug in our values:
______________________________
247 km² = 18 km * "y" ; solve for "y" (in units of "km") ;
_____________________________
18 y = 247 ;
___________________________________________________________
Divide each side of the equation by "18"; to isolate "y" on one side of the equation; and to solve for "y" :
___________________________________________________________
18 y / 18 = 247 / 18 ;
_____________________________________________
to get:
_____________________________________________
y = 13.7222222222222222...... km ; round to: 13.722 km
or; y = 13 13/18 km .

Answer:
Any value of x
<em></em>
Step-by-step explanation:
Given


Required
What value of x is 
Solving for f(g(x))


Solve the inner square



Solving g(f(x))





Equate f(g(x)) and g(f(x))


<em>This implies that </em>
<em> at any value of x</em>
Velocity is a speed and a direction.
The SI unit of speed is [meter per second].
Answer:
3x - 14
Step-by-step explanation:
f = 2x + 1
2x + 1 * g
g = x - 7
2x + 1 * x - 7 = 3x - 7
3x - 7 * 2 = 3x - 14

Hope this helped (:
also I assumed the $ = f at the begining so please let me know if I am wrong
