What are two numbers that add up to 70 without regrouping?

Mathematics

dedylja [7]3 years ago

Any of the tens i think (10=60, 20+50, etc.), but i am not too sure what is implied by regrouping. if i am right in thinking this only means "carrying" a digit after adding, then anything that adds up to 70 would work unless the sum of the digits in the ones place exceeded 9.

What is the Pythagorean triple generator and how does it work?​
r-ruslan [8.4K]

Answer:

Step-by-step explanation:

The Pythagorean Theorem states that

a^2+b^2=c^2

or that the two legs added together squared equal the hypotenuse squared

not: this only works with right triangles

Now Pythagorean triples are the set of sides that follow that rule

an example would be 3,4,5

why is it a Pythagorean triple?

well because it follows

a^2+b^2=c^2

3^2=9\\4^2=16\\16+9=25\\5^2=25

25=25
