Answer:

Let the number be x

Given:

11 + 5x = 20 + 2x

5x - 2x = 20 - 11

3x = 9

The number is 3.

Answer:

Step-by-step explanation:

Let x represent the number, and set up an equation:

5x + 11 = 2x + 20

Solve for x:

5x + 11 = 2x + 20

3x + 11 = 20

3x = 9

x = 3

So, the number is 3.

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
