The proper notation may depend on where you are. In the US, we like there to be one non-zero digit to the left of the decimal point, hence the appropriate form is ...
... 6.59×10¹¹
_____
Elsewhere, the "proper" form may require the first non-zero digit be placed to the right of the decimal point, as in 0.659×10¹². This is also the form used by some computer languages.
In Engineering usage, quite often the desired form is one that has the exponent be a multiple of 3, so the appropriate forms would be 659×10⁹ or 0.659×10¹².
Sometimes when you're doing problems using numbers in scientific notation, it can be convenient to scale the operands so the result comes out with no need for rescaling. For example, if you were to divide 100 by this number, you might write ...
... 100/(65.9×10¹⁰) ≈ 1.517×10⁻¹⁰
Without this "pre-scaling", you would get
... (10²)/(6.59×10¹¹) ≈ 0.1517×10⁻⁹ = 1.517×10⁻¹⁰
which requires rescaling the answer.
2(3x+4)
2(4x+6)
2(3x+8)
➷ Expand them all to see if you get the expression:
2(3x - 4) ==> 6x - 8
2(3x + 4) ==> 6x + 8
2(4x + 6) ==> 8x + 12
2(3x + 8) ==> 6x + 16
As you can see, the correct option is B. 2(3x + 4)
➶ Hope This Helps You!
➶ Good Luck (:

Answer:
So the second one
Step-by-step explanation:
2(3x-4) =6x-8
2(3x+4)=6x+8 2x3=6 2x4=8
2(4x+6)=8x+12
2(3x+8)=6x+16
