The length of the shorter side is 7 longer side is 12 7+7+12+12 is 38 and 7x12 is 84
        
             
        
        
        
I believe it is twenty eight. Ten is two thirds of fifteen. Twenty eight is two thirds of forty two. But I'm just assuming tbh
        
             
        
        
        
Answer:
f(1) = 42
Step-by-step explanation:
Step 1: Switch all x out to 1 for f(1) which would look like this: f(1)=4(1)^2+3(1)+13
Step 2: You would then simplify it starting with 4(1)^2 which would equal 4 squared which equals 16.
Step 3: After simplifying you would have f(1)=16+3+13
Step 4: You then just add and get 42
Hope this helped :D
 
        
             
        
        
        
This is a second-order ODE since the highest order derivative is 2 (from 

).
It's not linear because it doesn't take the form

and it's not possible to rewrite it as such.
