Expand and simplify <br> (V5-V2)(V2+V5)

gizmo_the_mogwai [7]

Answer:

3

Step-by-step explanation:

$(\sqrt{5} - \sqrt{2})(\sqrt{2} + \sqrt{5})\\\sqrt{5} (\sqrt{2} + \sqrt{5}) - \sqrt{2} (\sqrt{2} + \sqrt{5})\\\sqrt{5} * \sqrt{2} + \sqrt{5} * \sqrt{5} - \sqrt{2} * \sqrt{2} +\sqrt{2} * \sqrt{5}\\ \sqrt{5*2} + \sqrt{5*5} - \sqrt{2*2} - \sqrt{2*5}\\\sqrt{10} + \sqrt{25} - \sqrt{4} - \sqrt{10}$

plus root 10 and minus root 10 gets cancel . So,

$\sqrt{25} - \sqrt{4} \\\sqrt{5^{2} } - \sqrt{2^{2} }$

square and root gets cancel

12x + 3y = 9 solve for y

Vinvika [58]

Answer:

$\Longrightarrow: \boxed{\sf{y=3-4x}}$

Step-by-step explanation:

To solve for y, you have to isolate it on one side of the equation.

<h3>12x+3y=9</h3>

<u>First, you have to subtract by 12x from both sides.</u>

$\Longrightarrow:\sf{12x+3y-12x=9-12x}$

<u>Solve.</u>

$\Longrightarrow:\sf{3y=9-12x}$

<u>Then, you divide by 3 from both sides.</u>

$\Longrightarrow:\sf{\dfrac{3y}{3}=\dfrac{9}{3}-\dfrac{12x}{3}}$

<u>Solve.</u>

$\sf{\dfrac{9}{3}-\dfrac{12x}{3}}$

$\sf{\dfrac{9-12x}{3}}$

Use the distributive property.

$\underline{\text{DISTRIBUTIVE PROPERTY:}}$

<h3>⇒A(B+C)=AB+AC</h3>

9-12x=3(3-4x)

$\sf{\dfrac{3\left(3-4x\right)}{3}}$

<u>Divide the numbers from left to right.</u>

3/3=1

3-4x

<u>Then, rewrite the problem down.</u>

$\Longrightarrow: \boxed{\sf{y=3-4x}}$

<u>Therefore, the correct answer is y=3-4x.</u>

I hope this helps! Let me know if you have any questions.
