Answer:

Step-by-step explanation:
- If f(x) is in th form of f(x)=g(x)-h(x) then f'(x)=g'(x) - h'(x) 
- When f(x)=z(g(x)) then f'(x)= z'(g(x))g'(x) (called as chain rule) 
<u>using these information</u>:
g(x)=ln2x then g'(x)=
h(x)=In(3x - 1) then h'(x)=![\frac{(3x-1)'}{3x-1} =\frac{3}{3x-1}f'(x)=g'(x) - h'(x) =[tex]\frac{1}{x} - \frac{3}{3x-1} =\frac{-1}{3x^2-x}](https://tex.z-dn.net/?f=%5Cfrac%7B%283x-1%29%27%7D%7B3x-1%7D%20%3D%5Cfrac%7B3%7D%7B3x-1%7D%3C%2Fp%3E%3Cp%3Ef%27%28x%29%3Dg%27%28x%29%20-%20h%27%28x%29%20%3D%5Btex%5D%5Cfrac%7B1%7D%7Bx%7D%20-%20%5Cfrac%7B3%7D%7B3x-1%7D%20%3D%5Cfrac%7B-1%7D%7B3x%5E2-x%7D)
 
        
             
        
        
        
Answer:
a. True 
b. True
c. False
d. False
Step-by-step explanation:
<u>First Table</u>
Length=10 feet, Width=4 feet
Area =10 X 4=40 Square Feet
<u>Second Table</u>
The second table is half as long  as the first table.
Length =0.5 X 10 =5 feet
Area=5 X Width= 5w
The area of the second table is one  fourth the area of the first table.
Area of Second Table = X Area of first table
 X Area of first table
5w= X 40
 X 40
5w=10
Width of the Second table, w=2 feet
The following are true.
(a)The width of the second  table is 2 feet.
(b) The area of the second  table is 10 square feet.
