Answer:

x = -2

x = 8

Step-by-step explanation:

Excluded values are the ones which make the denominator zero

3x² + x - 10

3x² + 6x - 5x - 10

3x(x + 2) - 5(x + 2)

(x + 2)(3x - 5)

x² - 6x - 16

x² - 8x + 2x - 16

x(x - 8) + 2(x - 8)

(x - 8)(x + 2)

[(x + 2)(3x - 5)] ÷ [(x - 8)(x + 2)]

(3x - 5)/(x - 8)

So excluded values are 8, -2

Answer:

The percent markup is, $\simeq$ 60.89 % .

Step-by-step explanation:

A pair of shoes cost $ 22.99 to make, the local store sells them for $ 36.99.

So, the increased value for each pair of shoes,

= $ (36.99 - 22.99)

=$ 14

So, the percent markup is,

$\frac {14 \times 100}{22.99}$ %

$\simeq$ 60.89 %
