Answer:

${ x^2+3x-4}$

Step-by-step explanation:

Factor top and bottom.

The numerator is a difference of two squares, and the denominator is a quadratic.

$\frac{ {9x}^{2} - {(x}^{2} - 4)^{2} }{4 + 3x - {x}^{2} }$

= $\frac{ (3x+x^2-4)(3x-x^2+4) }{(1+x)(4-x)}$

= $\frac{ (x-1)(x+4) (1+x)(4-x) }{(1+x)(4-x)}$

If x does not equal -1 and does not equal 4, we can cancel the common factors in italics to give

= ${ (x-1)(x+4)}$

= ${ x^2+3x-4}$

The fencing William chooses costs $29.53 per foot, including installation. What will the fencing cost? Show your work.

TiliK225 [7]

Answer:

$C = 29.53x$

Step-by-step explanation:

Given

$Unit\ cost = \$29.53$

Required

The cost of fencing (C)

The cost is calculated as:

$C = Unit\ Cost * Perimeter\ of fencing$

Let:

$x \to Perimeter\ of fencing$

So, we have:

$C = Unit\ Cost * x$

$C = 29.53 * x$

$C = 29.53x$

<em>The question cannot be solved further since the dimension of the fence is not given</em>

<em>If you know the dimension, calculate the fence perimeter and substitute the value for x</em>
