Answer:
-5
Step-by-step explanation:
Since it is a square, the diagonals are congruent. If a square is split like this, it becomes two congruent right triangles. The relationship between the sides and hypotenuse is a 1:

ratio. So if the diagonal of a square is 14 cm, then the side length would be 14/

, which is approximately 9.899. I don't understand what the answer choices are, but you should be able to square root the numbers to determine the answer.
It would be 10x10 =100 or in other word 10 times itself. Also known as 10 with the 2 hanging over the 10.
Answer:
12x -2 = 22
12x = 22 +2
12x = 24
x = 24/12
x= 2
therefore, the vale of x =2.
The middle is zero to the left starting at one go to -5 or whatever the lines stop at (don't forget those are the negative).
Then for the right do the same but positive.
