We are given:

-14

To simplify this inequality, we can add 2 to all three sides. When we do that, we are left with:

-12

After we simplify that, we can divide all sides by -6. Here is what we get:

\frac{-12}{-6}

When you simplify, your final answer will be:

2>x\geq-4

Suppose you have 54 feet of fencing to enclose a rectangular dog pen. The function a=27x-x^2, where x=width, gives you the area
andrew-mc [135]
For maximum area, we take first derivative and then equalize it to zero
<span>A(x) = 27x- x^2 </span>
<span>A'(x) = 27 - 2x </span>

<span>Set that equal to zero and solve for x : </span>
<span>27 - 2x = 0 </span>
<span>27 = 2x ......................... [ added 2x to both sides ] </span>
<span>13.5 = x ........................ [ divided both sides by 2 ] </span>

So the area will be
<span>A = 27(13.5) - (13.5)^2 </span>
<span>   = 364.5 - 182.25 </span>
<span>   = 182.3 ft^2 </span>
