What Pythagorean triple is

generated by multiplying each
integer in the Pythagorean triple
(20, 21, 29) by 5?

1 answer

To generate a new Pythagorean triple by multiplying each integer in the given triple (20, 21, 29) by 5, we perform the following calculations:

  1. Multiply 20 by 5: \[ 20 \times 5 = 100 \]

  2. Multiply 21 by 5: \[ 21 \times 5 = 105 \]

  3. Multiply 29 by 5: \[ 29 \times 5 = 145 \]

So, the new Pythagorean triple is (100, 105, 145).

To verify that (100, 105, 145) is indeed a Pythagorean triple, we can check if \(100^2 + 105^2 = 145^2\):

Calculating \(100^2\): \[ 100^2 = 10000 \]

Calculating \(105^2\): \[ 105^2 = 11025 \]

Adding these two results: \[ 10000 + 11025 = 21025 \]

Now calculating \(145^2\): \[ 145^2 = 21025 \]

Since \(100^2 + 105^2 = 145^2\), we confirm that (100, 105, 145) is a valid Pythagorean triple.

Thus, the Pythagorean triple generated by multiplying (20, 21, 29) by 5 is: \[ \boxed{(100, 105, 145)} \]
