diagonal = 9√2 ≈ 12.73
the diagonal splits the square into 2 right triangles with the hypotenuse being the diagonal of the square
using Pythagoras' identity
d = √(9² + 9²) = √162 = 9√2 ≈ 12.73 ( to 2 dec. places )

Answer:
x = 1
Step-by-step explanation:
2x−2+6x=6
Combine 2x and 6x to get 8x.
8x−2=6
Add 2 to both sides.
8x=6+2
Add 6 and 2 to get 8.
8x=8
Divide both sides by 8.
x = 
Divide 8 by 8 to get 1.
x=1

Options ???????????????????????????????????????
the answer would be -21 because you would have to multiply the 24 by -7 because it is dividing on the other side. and then you would have to divide the number you get by 8
so basically, it will look like this step by step:
-7/8x=24
8x=24*-7
8x=-168
x=-168/8
x= -21
