Answer:
20
Step-by-step explanation:
Using the rule of radicals
× 
⇔ 
Simplify
= 
= 
× = 2
Thus
6 + 8
= 6(2 ) + 8
= 12 + 8
= 20

Answer: 29</h3>
=================================
Work Shown:
Solve the second equation for f(b)
2f(b) = 28
f(b) = 28/2
f(b) = 14
----------
Plug in x = b and solve for b
f(x) = 3x-1
f(b) = 3b-1 ... replace every x with b
14 = 3b-1 ..... plug in f(b) = 14
3b-1 = 14
3b = 14+1
3b = 15
b = 15/3
b = 5
-----------
f(x) = 3x-1
f(2b) = 3(2b)-1 .... replace every x with 2b
f(2b) = 3(2*5)-1 .... plug in b = 5
f(2b) = 3*10-1
f(2b) = 30-1
f(2b) = 29

Step-by-step explanation:
yes
Answer:
comparing fossils with other engerys:
Most alternatives energy sources doesn't have as much pollution produce like fossil fuel does,
Fossil comes from underground or persevered by nature, when others can be made by renewable resources, such as Wind(windmills) , sun (solar), and water (those rolly things)
