Answer:

Step-by-step explanation:

3x-6y=-6..........(1)

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

Making y as subject in (2)

y = 2x + 4.......(3)

Substituting (3) into (1)

3x - 6(2x + 4) = -6

3x - 12x - 24 = -6

-9x = -6 + 24

-9x = 18

x = 18/-9

x = -2

Substitute x = -2 into (3)

y = 2x + 4

y = 2(-2) + 4

y = -4 +4

y = 0

What is the perimeter of the triangle
damaskus [11]

Answer:30 centimeters

Step-by-step explanation:

The bigger square with an area of 144 cm squared has a perimeter of 100 with each side equal to 25. You find this by seeing that 25 times 25 equals the area of the square. Same thing with the smaller square 5 times 5 equals 25. Now that we have the perimeter for the sides that are connected to the square (25) and (5), multiply those together just as you would with finding the area of a square. (25)(5)=60. Since this is a triangle you divide your answer in half which is 30.
