Pythagorean theorem: find the length of a side of a square with a diagonal length of 12

The answer to your question is the length of a side = 6

Step-by-step explanation:

Data

Square with a diagonal of 12

In a square the legs measure the same so, leg = x

Process

1. Write the Pythagorean theorem

                   c² = a² + b²

2.- Substitute values

                   12² = x² + x²

3.- Simplify

                  144 = 2x²

                   144/2 = x²

                   72 = x²

                   x = √72

4.- Result

                   x = 6√2

answer: idk

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
