15, since 15*2 = 9*2 + 12*2
5 will make 12 and 13 a Pythagorean triad.
this is a pythagorean triple and c2=169 so c=13 25+144=169=132
A Pythagorean triple is a group of three whole number which can be the sides of a right angled triangle, eg: (3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17), (9, 40, 41), (11, 60, 61), (12, 35, 37), (13, 84, 85), (16, 63, 65), (20, 21, 29), (28, 45, 53), (33, 56, 65), (36, 77, 85), (39, 80, 89), (48, 55, 73), (65, 72, 97)
Yes
The sequence appears to alternate between adding and subtracting numbers. The pattern seems to be +11, -7, +5, -2, +6. Following this pattern, the next number in the sequence would be +3 from the previous number, which would be 21.
To determine if 9, 15, and 12 form a Pythagorean triple, we check if the square of the largest number equals the sum of the squares of the other two. Here, 15 is the largest number. Calculating, we have (15^2 = 225) and (9^2 + 12^2 = 81 + 144 = 225). Since both sides are equal, 9, 15, and 12 do form a Pythagorean triple.
No, the numbers 9, 12, and 15 do not form a Pythagorean triple. A Pythagorean triple consists of three positive integers (a), (b), and (c) such that (a^2 + b^2 = c^2). In this case, if we take 15 as the largest number, (9^2 + 12^2 = 81 + 144 = 225), which equals (15^2). Therefore, 9, 12, and 15 do indeed form a Pythagorean triple.
No. 122 + 162 = 400 = 202 so 12, 16, 20 would be a Pythagorean triple, but 12, 16, 18 would not.
It is: 13
yes.
Pythagorean triples: 3, 4 and 5 or 5, 12 and 13 are two of them
Because: 52+122 = 132
The combination 5, 12 and 13 is a Pythagorean triple.
5 will make 12 and 13 a Pythagorean triad.
No. 7*7 = 49 12*12 = 144 14*14 = 196 49 + 144 = 193, which does not equal 196
3-4-5 5-12-13 are the most common 4^2 + 5^2= 16+25=41 which is prime.
The letter is L and the number is 12.
