Answer:

x is 4.30 and 0.697

Step-by-step explanation:

Quadratic formular:

$x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} \\$

a » 1

b » -5

c » 3

$x = \frac{ - ( - 5)± \sqrt{ {( - 5)}^{2} - (4 \times 1 \times 3)} }{(2 \times 1)} \\ \\ x = \frac{5± \sqrt{13} }{2}$

Therefore, values of x :

$x = \frac{5 + \sqrt{13} }{2} \: \: and \: \: \frac{5 - \sqrt{13} }{2} \\ \\ x = 4.30 \: \: and \: \: 0.697$

The pressure is 39 Pa if the volume is expanded to 168L and the pressure, P, of a gas varies inversely with its volume, V.

<h3>What is a proportional relationship?</h3>

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

We have:

The pressure, P, of a gas varies inversely with its volume, V.

P ∝ 1/V

P = k/V

k is the constant.

If P = 126 Pa and V = 52 L

126 = k/52

k = 6552

P = 6552/V

Plug V = 168 L

P = 6552/168 = 39 Pa

Thus, the pressure is 39 Pa if the volume is expanded to 168L and the pressure, P, of a gas varies inversely with its volume, V.
