$x = +2\sqrt{2}i , {\textrm{ or}} x= -2\sqrt{2}i$

Step-by-step explanation:

Here,the given expression is : $5 + x^{2} = 2x^{2} + 13$

Now simplifying the expression, we get

$5 + x^{2} = 2x^{2} + 13$

⇒ $x^{2} - 2x^{2} = 13 - 5$

or, $-x^{2} = 8$

⇒ $x^{2} = -8 \\ or, x^{2} + 8 = 0$

Now, Since here the roots are NOT REAL but imaginary.

So, try and solve this by $x = \frac{b \pm \sqrt{b^{2} - 4ac } }{2a}$

here, a = 1, b = 0 and c = 8

So, solving this, we get $x = \frac{\pm \sqrt{-32} }{2} = \frac{\pm 4\sqrt{2} }{2}$

⇒ $x = +2\sqrt{2}i , {\textrm{ or}} x= -2\sqrt{2}i$

Given:
5 horses with a combined weight of 6,240 pounds
horse trailer has a limit of 8,000 pounds of horse and tacks.

Find the weight of tack, t, for each horse that Cari can allow.

5t + 6,240 < 8,000

5t + 6,240 < 8,000
- 6,240 -6,240
5t < 1,760
÷5 ÷5
t < 352

Each horse can carry a tack that weighs no more than 352 pounds.

Any tack that weighs beyond 352 pounds is will exceed the maximum carrying capacity of the horse trailer.
