3 0

Step-by-step explanation:

simply the first one.

-9x -6y = 39 is nothing else than

3x + 2x = -13 multiplied by -3

which leaves the values and solutions unchanged, as we could simply divide by -3 again and end up with the original system and its solution.

What is the length of a diagonal of a square with a side length of 6?

vfiekz [6]

By the Pythagorean Theorem:

d^2=x^2+y^2, where x and y are the dimensions of the rectangle, however this is just a square, so x=y=s so

d^2=s^2+s^2

d^2=2s^2, and we are told that s=6 so

d^2=2(6^2)

d^2=2(36)

d=√(2(36))

d=6√2 units

d≈8.49 units (to nearest hundredth of a unit)
