Answer:
D 18
Step-by-step explanation:
3z + 6
Let z=4
3*4 +6
Multiply first
12+6
Then add
18
Answer:
First one can
Second one can not
Step-by-step explanation:
13² = 5² + 12²
169 = 25 + 144
169 = 169 is a true statement
15² = 11² + 12²
225 = 121 + 144
225 = 265 is a false statement
So, not a right angle triangle
Multiplying every length of a Pythagorean triple by the same whole number results in a Pythagorean triple.
<h3>How to verify if a triangle form Pythagorean triple?</h3>
Pythagoras's principle follows the rule:
c² = a² + b²
where
- a and b are the legs
- c is the hypotenuse side.
Therefore, Pythagorean triples are a² + b² = c² where a, b and c are the three positive integers. The most known and smallest triplets are (3,4,5).
If we reduced the length of the side of the triangle with the greatest common factor, it should give us 3, 4, 5.
Hence,
21, 28 and 35 has greatest common factor as 7
21 / 7 , 28 / 7 and 35 / 7
3, 4, 5
Hence, multiplying every length of a Pythagorean triple by the same whole number results in a Pythagorean triple.
