Answer:

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

equation
PEMDAS

<h3>let's solve:</h3>

parimeter of a square:4a

according to the question

$\sf 4(8x + 2) = 488$

divide both sides by 4:

$\sf \frac{4(8x + 2) }{2}= \frac{488}{2} \\ \sf \frac{ \cancel4 ^{} (8x + 2)}{ \cancel{4}} = \frac{ \cancel{488} \: ^{122} }{ \cancel{ \: 2}} \\ 8x + 2 = 122$

cancel 2 from both sides:

$\sf 8x + 2 - 2 = 122 - 2 \\ \sf 8x = 120$

divide both sides by 8

$\sf\frac{8x}{8} = \frac{120}{8} \\ \sf \therefore \: x = 15$

4/1 sqrt3-sqrt2 rationalize?

Triss [41]

$\dfrac{4}{\sqrt3-\sqrt2}=\dfrac{4}{\sqrt3-\sqrt2}\cdot\dfrac{\sqrt3+\sqrt2}{\sqrt3+\sqrt2}=\dfrac{4(\sqrt3+\sqrt2)}{(\sqrt3)^2-(\sqrt2)^2}\\\\=\dfrac{4\sqrt3+4\sqrt2}{3-2}=4\sqrt3+4\sqrt2$
