Im gonna asume you mean side, so 1 foot = 12 inches (:
2x + 10...the common number between these 2 terms is 2...so factor the 2 out
2(x + 5) <==
k<2(3.5) or simplified k<7
<h3>
Answer:</h3>

<h3>
Step-by-step explanation:</h3>
We know that
, so substitute that into the equation. 
With negative powers, instead of making the result negative, you divide one by it. Mathematically speaking,
. This makes our equation: 
Finally, simplify the exponent. 
The given equation is:

We have to find, which of the given set of parametric equations given in the options, result in the above equation:
The correct answer would be option A.
The equations in option A are:

From first equation we can see that 5t is equal to x. Using the value of 5th in second equation, we get the equation as:
Therefore, the correct answer is option A
