0.2(6x+1)/3.6=0.5x/9
Solution
(1.2x + 0.2)/3.6 = 0.5x/9
Cross multiplying, we get
9(1.2x + 0.2) = 3.6 * 0.5x
10.8x + 1.8 = 1.8x
10.8x - 1,8x = -1.8
9x = -1.8
Dividing both sides by 9, we get
x = - 0.2
That's the answer.
Thank you.

The result of the simplified polynomial in standard form is 26x-67-x^2.
Given that,
- There is (x-8)^2.
- And, 10x - 3
- The above (x - 8)^3 should be subtracted from 10x-3.
Based on the above information, the equation be like
= (10x - 3) - (x - 8)^2
= 10x - 3 -(x^2-16x+64)
= 10x - 3-x^2+16x-64
= 26x-67-x^2
Therefore we can conclude that the result of the simplified polynomial in standard form is 26x-67-x^2.

Check the picture below, so the parabola looks more or less like so, with a "p" distance of 3 and the vertex at the origin, keeping in mind the vertex is half-way between the focus point and the directrix.

If 
, then by definition of absolute value
On the other hand, if 
, then
So, the overall solution to the inequality is interval union
