8 0

Answer:

Step-by-step explanation:

-3x - 5 = 16

add 5 to both sides of the equation

-3x = 21

divide both sides by -3

x = -7

---------------------

-4(y - 2) = 12

distribute the -4 to everything in the parentheses

-4y + 8 = 12

subtract 8 from both sides of the equation

-4y = 4

divide both sides of the equation by -4

y = -1

mariarad [96]

Answer:

8 $\sqrt{13}$ units

Step-by-step explanation:

We know that:

P = 4a

We can find one side by distance formula:

a = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
a = $\sqrt{(10 - 4)^2+(-5+9)^2} = \sqrt{36+16} = \sqrt{52} = 2\sqrt{13}$

Then the perimeter is:

P = 4*2 $\sqrt{13}$ = 8 $\sqrt{13}$ units
