Answer:

x = 12

Step-by-step explanation:

xyz = (3y + z)² - (3y - z)²

xyz = [(3y + z) + (3y - z)] × [(3y + z) - (3y - z)]

∵ {a² - b² = (a + b)(a - b)}

xyz = (6y) × (2z)

xyz = 12yz

x = 12yz/yz

x = 12

Hope it Helps!

Solution

 xyz\: =\: (3y\: +\:z)^{2}\:-\:(3y\:-\:z)^{2}

 xyz \: = \: 9y^{2}\: +\: z^{2}\: + \: 6yz - (9y^{2}\: +\: z^{2}\: - \: 6yz)

 xyz \: = \:\cancel{9y^{2}} \: +\: \cancel{z^{2}} \: + \: 6yz - \cancel{9y^{2}} \: - \: \cancel{z^{2}} \: + \: 6yz

 xyz \: = \: 6yz \: +\: 6yz

 xyz \: =\: 12yz

 x\: =\: \dfrac{12yz}{yz}

ANSWER

\boxed{x\: =\: 12}
