Answer:

In other words, the base must be at least 9 feet long. 
Step-by-step explanation:
The schools wants the height of the triangle to be eight feet, and the area of the logo to be at least 36 square feet. 
Recall that the area of a triangle is given by: 

Since we want to area to be at least 36 square feet: 

We are given that the height is eight feet. Substitute: 

Simplify: 

Divide both sides by four. Hence, our inequality is: 

In words, this means that the base must be at least 9 feet long. 
 
        
             
        
        
        
(3,0) and (0,-9)
Explanation: type the equation in a graphing calculator and the answer is the points where the line crosses the x and y axis
 
        
        
        
open the parenthes. and then after that you'll get 27+12x-15. if you simplify that then you'll get 12x+12
 
        
                    
             
        
        
        
For this case we have the following expression:

We apply distributive property, which by definition establishes that:

So:
