Answer:

x = 4.625, y = 1.375

Step-by-step explanation:

I am assuming that the second equation is 4x - 4y = 13.

2x+2y=12

4x-4y=13

Multiply first equation by -2:-

-4x - 4y = -24 Add this to the second equation to eliminate x:-

-8y = -11

y = 11/8 = 1.375

Plugging this into the first equation:-

2x + 2(1.375) = 12

2x = 9.25

x = 4.625

find the length of each isosceles right triangle when the hypotenuse is of the given measure given 8cm

Wewaii [24]

It is given that the triangle is isosceles right triangle . And in an isosceles right triangle the legs are equal . Let each leg be of x units. Now we use pythagorean identity, which is

$a^2 +b ^2=c^2$

$x^2 +x^2 = 8^2$

$2x^2 = 64$

$x^2 = 32$

$x = 4 \sqrt 2$

So the length of each leg is $4 \sqrt 2 .$
