MARKING AS BRAINLIEST! LAST ATTEMPT! ) show ur work

matrenka [14]

Answer:

$\sqrt{28} =\sqrt{(7)(4)} =2\sqrt{7} \\\sqrt{40} =\sqrt{(10)(4)} =2\sqrt{10} \\\sqrt{108} =\sqrt{(36)(3)} =6\sqrt{3} \\\sqrt{125} =\sqrt{(25)(5)} =5\sqrt{5}$

$-6\sqrt{81} =-6(9)=-54$

$\sqrt{80} =\sqrt{(16)(5)} =4\sqrt{5)} \\3\sqrt{60} =3\sqrt{(15)(4)} =(3)(2)\sqrt{15} =6\sqrt{15}$

$-\sqrt{200} =-\sqrt{(100)(2)} =-10\sqrt{2}$

$4\sqrt{320} =4\sqrt{(64)(5)} =(4)(8)\sqrt{5} =32\sqrt{5}$

Hope this helps

NEED HELP GIVING BRAINLIEST

Pie

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We need two points through which the line passes to find the slope:

$(0, -4)\\(1,0)$

We found the slope:

$m = \frac {y2-y1} {x2-x1}\\m = \frac {0 - (- 4)} {1-0} = \frac {4} {1} = 4$

So, the equation is of the form:

$y = 4x + b$

We substitute a point to find "b":

$-4 = 4 (0) + b\\-4 = b$

Finally, the equation is:

$y = 4x-4$
