Answer:
Yes, this is a right triangle
Step-by-step explanation:
Plug the values into the pythagorean thm. 
1.5^2 + 2^2 = 2.5^2
2.25+4=6.25
6.25=6.25
 
        
             
        
        
        
Take .50 and multiply it by 2 because it doubled. then multiply that by 6 or 12 to get your answer
        
                    
             
        
        
        
Answer:
Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is one solution that is true for both equations. If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations.

A)24 boards/1 * 47.5 inch/boards * 1 ft/12in = 95 ft.
according to dimensional analysis the answer is 95 ft.
b) 95/8 is approximately 12 so 12 boards are needed.
