Common Pythagorean triples include (3, 4, 5) (5, 12, 13) (7, 24, 25) (9, 40, 41) The only Pythagorean triple that is an arithmetic sequence is (3, 4, 5), so any arithmetic sequence that is a Pythagorean triple must be a multiple of that, such as (9, 12, 15) or (15, 20, 25).
The arithmetic sequences of selections B and D are unrelated to the (3, 4, 5) triple, so cannot be Pythagorean triples. For selection A, we know that 9² + 11² = 81 + 121 = 202 > 14², so that is not a right triangle.
If A is equal to 30, and A+B equals 42. That means B equals 12. So, if the value increased with the same rate of change, it would be 54. This is because 30 plus 12 is 42. 42 plus 12 would equal 54.
Easy ill tell u and then do a equation first sense it has - it means u have to subtract alright it goes like this. 17,1 9,3 -------- 7,8 and this is ur answer as u see in my equation ur welcome only give me brainiest only if im right
