Answer:
21/20
Step-by-step explanation:
you find a common multiple for the 4 and 5, and multiply to get it. In this case, it would be 20. So, you multiply 1 and 4 by 5 so it would be 5/20. And multiply 4 and 5 by 4 to get 16/20. 5/20+16/20 is 21/20.
 
        
                    
             
        
        
        
f(a + 2)= 3a + 
substitute x = a + 2 into f(x)
f(a + 2) = 3(a + 2) +
            = 3a + 6 +  = 3a +
 = 3a + 
 
        
             
        
        
        
1/f(-4) should be the answer

Answer:
   no
Step-by-step explanation:
The angle of the ramp as designed by the planning department is ...
   tan(angle) = (3 ft)/(25 ft)
   angle = arctan(3/25) ≈ 6.84°
This angle exceeds the required 4.75°, so does not meet code.
