The x-intercepts are: -0.5 and 2.
        
             
        
        
        
The height of the kite is 3 feet. Here’s 
why;
We know that BH=2A (base times height is equal to 2 times the area) of any given triangle. 
Lets plug in values;
BH=2A
4(H)=2(6)
Then simplify;
4(H)=12
Flip the equation to find the missing value;
12 divided by 4 is 3.
Check your work;
4(3)=6(2):
12=12
The height of the kite is 3 feet.
        
             
        
        
        
For example, the additive inverse of 12 is –12. The additive inverse of –3 is 3. Formally, the additive inverse of x is –x. Note: The sum of a number and its additive inverse is 0.
        
             
        
        
        
First thing we gotta do is find the unit rate:
800 divided by 2.5 = 320
And now your problem is complete! The unit rate or square foot per hour is 320 square feet per hour!
