Answer:
It is subtracting 5 every time hope that helps!
Answer: 4a^2-2b^2 (I think this is right)
Step-by-step explanation:
Using the order of operations I started by multiplying both of the sides separately. The left side of the equation becomes 2a^2-b^2-ab while the right becomes 2a^2-b^2+ab. Then I put the sides together to add them and after combining like terms it becomes 4a^2-2b^2.
the population will reach 8 billion by 2012 ,as calculated by properties of logarithm.
<h3>What is Logarithm?</h3>
- The opposite of exponentiation is the logarithm.
- This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.
- A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.
Given:
- y = 6.72 (
), where
- y = population in billions
- x = time in years
To find: Year when population is 8 billion, i.e., y = 8.
Finding:
8 = 6.72 ( )
=> 
Taking log on both sides
=> 
=> log(1.19) = x (log 1.014) (as 
)
=> 
= x
=> x = 
=> x = 12.58
Hence, the population will reach 8 billion by 2012 ,as calculated by properties of logarithm.

Hello there ^ _ ^
When you have 4m - 4 = 4m
The m means that you are looking for a number, but the number is unknown and you usually need to find it.
M is like blank space.
For example : She .... two apples
The blank space can be eats. right?
well it is the same thing for M
4..-4 = 4..
The blank space is missing a letter and you need to go look for that letter or number.
Now, let me solve it for you just in case if you would like to know how to find that unknown number.
4m - 4 = 4m
You need to put the common terms together ( the common terms are the one that looks alike)
we have two 4m, right ? so we gonna put them together.
-4 = 4m - 4m
-4 = 0
Add 4 to both sides
-4+4 = 0+4
0 = 4
In this case there are no solutions.
This mean that there no number you can replace m with that will make them equal. Does that make sense ?
I hope this help! Comment if you have more questions!
