<em>1. x = - 7/3 = - 2 1/3</em>
<em>2. x = -2</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em />
<em>3x + 12 = - 6x - 9</em>
<em>3x + 6x = - 12 - 9</em>
<em>9x = - 21</em>
<em>x = - 21⁽³/9</em>
<em>x = - 7/3</em>
<em>x = - 2 1/3</em>
<em />
<em>12x + 20 = 2x</em>
<em>12x - 2x = - 20</em>
<em>10x = - 20</em>
<em>x = - 20/10</em>
<em>x = - 2</em>

<em>Good luck !</em>
<u>Answer-</u>
At
the curve has maximum curvature.
<u>Solution-</u>
The formula for curvature =

Here,

Then,

Putting the values,

Now, in order to get the max curvature value, we have to calculate the first derivative of this function and then to get where its value is max, we have to equate it to 0.

Now, equating this to 0






Solving this eq,
we get 
∴ At
the curvature is maximum.
(1) 6 1/3 = 76/12
2 3/4 = 33/12
___________+
109/12
divide and get 9 1/12
-----------------------------------
(2)3 1/2 = 43/12
5 1/2 = 66/12
*from first answer* 109/12
add and you get 218/12
divide and get the answer 18 1/6
Hope this helps you!
