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.
The appropriate selection is ...
C. 7, 24, 25
You need to clarify whether you need the x or the y or both
According to the order of operations, evaluate all multiplication first.
10-45+-12
Then add and subtract from left to right
-35-12
-47
Final answer: -47
Well, lets add 0.125 to 4.1.
We would get 4.225.
Finally we can check.
4.225-0.125= 4.1
How did we get it? What i did is I did the opposite. Instead of subtracting 0.125 I added it.
N= 4.225
It has 90 degrees so it's right
And none of the sides are equal so it's scalene
