<u>Parallel lines</u> are lines that run side-by-side without touching or intersecting! 
<u>Perpendicular lines</u> intersect/cross and can also make 90° angles (those little green boxes in the picture) in their corners!

Answer:
c
Step-by-step explanation:
 
        
             
        
        
        
<span>f(x)=âš(4x+6)
g(x)=âš(4x-6)
This is what we are given to work with, originally. Now, for the next part, we are asked to add the functions f(x) and g(x) together - and this is just what you do! You add the functions together, and then combine like terms.
(f+g)(x)=âš(4x+6)+âš(4x-6) --> âš(8x) + 6 - 6 :: and the 6's cancel each other, while the root 4x's add... and you have...
(f+g)(x)=âš(8x)
Thank you very much.</span>
        
             
        
        
        
1+2=3. 4/10+2/10=6/10. 3+ 6/10=3 6/10
        
             
        
        
        
It would be 6 in. Because if you separate 60 into two parts such that one part will exceed the other part by 36
