Answer:

The sum of two irrational numbers is always a irrational number

Step-by-step explanation:

You can take the number π+π and the result still is an irrational number,

you can also probe with a more common number like √2 and √3, thus, we always have an irrational result.

Remember, an irrational number is the one that can not be expressed as a fraction between two integers numbers, or has an infinite number of non repetitive decimals.

Answer:

When you add two irrational numbers together, you get an irrational number. It's like if you do pi+pi and obviously you still can't write it as a fraction. Hope this helps.

I WILL MAKE YOU BRAINLIEST!!!!Triangle STU is formed by the three squares D, E, and F:

Which statement best explains the relationship between the sides of triangle STU?

ST + TU = SU, because 36 + 64 = 100

(ST)2 + (TU)2 = (SU)2, because 102 + 62 = 82

ST + TU = SU, because 102 + 62 = 82

(ST)2 + (TU)2 = (SU)2, because 36 + 64 = 100
