Answer:
Step-by-step explanation:All other quantities of physical objects can be expressed as combinations of these fundamental quantities. For example, density is volume per mass. It can be expressed as a combination of the fundamental quantities mass (M) and length (L), M/(L × L × L) = M/L3. Similarly, area is a function of length, L × L = L2.
 
        
             
        
        
        
Answer:
B, C, D
Step-by-step explanation:
Square roots are not in polynomials
 
        
             
        
        
        
A negative sign and a negative sign next to each other is a positive sign ex..
 -14 - -3
= -14 + 3 
= -11
a negative sign and a positive sign next to each other is a positive sign ex..
 -14 + -3 
= -14 - 3
= -17
the bigger a negative number the smaller it is 
the bigger a positive number the larger it is
which supports the rule if you are subtracting the
number will become smaller and if you are adding 
the number will become larger
        
             
        
        
        
F(a)=2a+8
f(a+h)=2(a+h)+8=2a+2h+8
(f(a+h)-f(a))/h=(2a+2h+8-2a-8)=2h/h=2
