Which expression is the simplest form -(4x+y)+2(x-3y)

Verdich [7]

Answer:

- 2x - 7y

Step-by-step explanation:

Given

- (4x + y) + 2(x - 3y)

Distribute both parenthesis, noting that the first is distributed by - 1

= - 4x - y + 2x - 6y ← collect like terms

= (- 4x + 2x) + (- y - 6y )

= - 2x + (- 7y) = - 2x - 7y

An element with mass 330 grams decays by 25.5% per minute. How much of the element is remaining after 5 minutes, to the nearest

babymother [125]

Equation: 330-.255(5)=X. Multiply: .255(5)=1.275, 330-1.275=X. Subtract: 330-1.275=328.725 or 328.73 :)

Guys need help its surd one <br><img src="https://tex.z-dn.net/?f=5%20%5Csqrt%7B3%20%5Cdiv%202%20%5Csqrt%7B3%20-%20%20%5Csqrt%7B

sergey [27]

Answer:

Step-by-step explanation:

$\displaystyle \Large \boldsymbol{} 5\cdot \sqrt{3:2\sqrt{3-\sqrt{2} } } =\\\\\\ 5\cdot \sqrt{\frac{3}{2\sqrt{3-\sqrt{2} } } \cdot \frac{2\sqrt{3+\sqrt{2} } }{2\sqrt{3+\sqrt{2} } } } = \\\\\\5\cdot \sqrt{\frac{6\sqrt{3+\sqrt{2} } }{4\cdot \sqrt{9-2} } } =5\sqrt{\frac{6\sqrt{3+\sqrt{2} } }{2\sqrt{7} } }$

But if the condition would be like this

$\displaystyle \Large \boldsymbol{} 5\cdot \sqrt{3:2\sqrt{3-\boldsymbol2\sqrt{2} } } =\\\\\\5\cdot \sqrt{\frac{3}{2\cdot \sqrt{\underbrace{2+1-2\sqrt{2} \cdot \sqrt{1} }_{(\sqrt{2} -1)^2} } }} =\\\\\\5\cdot \sqrt{\frac{3}{2\cdot (\sqrt{2}-1) } } } = \\\\\\ 5\cdot \sqrt{\frac{3}{2(\sqrt{2}-1 )} \cdot \frac{\sqrt{2} +1}{\sqrt{2}+1 }} =5 \sqrt{\frac{3}{2(2-1)} } =\boxed{5\sqrt{1,5} }$
