Which expression is equal to 254−−√−424−−√ ?

hichkok12 [17]

Answer:

$-2\sqrt{6}$

Step-by-step explanation:

<u><em>The correct expression is</em></u>

$2\sqrt{54}-4\sqrt{24}$

we know that

$54=(2)(3^3)=(3^2)(2)(3)=(3^2)(6)$

$24=(2^3)(3)=(2^2)(2)(3)=(2^2)(6)$

substitute in the expression above

$2\sqrt{(3^2)(6)}-4\sqrt{(2^2)(6)}=2(3)\sqrt{6}-4(2)\sqrt{6}=6\sqrt{6}-8\sqrt{6}=-2\sqrt{6}$

Write the point from of the equation for a line that passes through (6,—1) with a slope of 2

Paraphin [41]

Answer:

y = 2x-13

Step-by-step explanation:

The equation for a line is

y = mx+b where m is the slope and b is the y intercept

y = 2x+b

We know a point so we have a y and an x, so we can solve for b

-1 = 2(6) +b

-1 =12+b

Subtract 12 from each side

-1-12 = 12-12+b

-13 =b

Substitute this into y = 2x+b

y = 2x-13
