150x100= 15,000 square meters
150x2= 300
100 + 300 = 400 meters of fencing

Answer:
   100 J
Step-by-step explanation:
Kinetic energy is jointly proportional to mass and the square of the velocity.
   KE = 1/2mv²
   KE = 1/2(50 kg)(2 m/s)² = 100 J
Juan has a kinetic energy of 100 joules.
 
        
             
        
        
        
The x-intercept is when y=0, so we plug that in our equation,

. +12 on both sides to get 

. Divide by -8 to get
