Answer:

x=30/7

Step-by-step explanation:

7x+12+3x=-6(x-7)+9x

10x+12=-6x+42+9x

10x+12=3x+42

10x-3x+12=42

7x+12=42

7x=42-12

7x=30

x=30/7

Which special version of the Pythagorean Theorem can you use to find the length of any squares diagonal, d, using only the lengt

EleoNora [17]

The square's diagonal is the triangle's hypotenuse.

The Pythagorean theorem is = $a^{2}+b^{2}=c^{2}$

Here, 'c' is the hypotenuse and 'a' and 'b' are the two sides of the triangle.

As the side is given 12 inches, so this becomes

$12^{2}+12^{2}=d^{2}$

$144+144=d^{2}$

$d^{2}=288$

$d=\sqrt{288}$

$d=16.97$ inches
