Answer:

(x-4)(y+4)

Step-by-step explanation:

First you group the expression to get (xy+4x)+(-4y-16)

then factor to get x(y+4)-4(y+4)

and factor again to get (x-4)(y+4)

Answer:

b = √32

Step-by-step explanation:

The Pythagorean theorem tells you the relation between the side lengths is ...

2² + b² = 6²

b² = 36 -4 = 32

b = √32

_____

<em>Additional comment</em>

This radical can be simplified by removing a square from under the radical.

$b = \sqrt{32}=\sqrt{16\cdot2}=\sqrt{16}\cdot\sqrt{2}=4\sqrt{2}$

NARA [144]

Answer:

(x,y)=(-10, -30)

Step-by-step explanation:

x/4 -y/12 = 0

--> x/4 = y/12

substitute into the first eq.

x/4 + y/12 = -5

y/12 + y/12 = -5

2y/12 = -5

y= (-5) * 12/2 = -30

solve for x, x/4 = (-30)/12

x=4* (-30)/12 = -10
