40 inches because a rectangle has 2 sets of parallel lines and if the width and length are 10 then you just have to add up all the sides.
        
             
        
        
        
Answer:
w=4
Step-by-step explanation:
2(48)+2(8w)+2(6w)=208
1) Start by Distributing the value outside of the parenthesis:
96+16w+12w=208
2) Combine alike terms:
96+28w=208
3) Subtract 96 from both sides:
28w=112
4)Divide both sides by 28 to isolate w:
w=4

Answer:
   
Step-by-step explanation:

__
The applicable rules of logarithms are ...
   log(ab) = log(a) +log(b)
   log(a/b) = log(a) -log(b)
   log(a^b) = b·log(a)

Answer:
c. -2
Step-by-step explanation:
Since f(x) is the regular graph. Since the inverse function flips the x and y coordinates, f inverse of 4 is actually where y=4, not x=4. so the x coordinate where y is 4 is -2.
