Answer: Option 'B' is correct.

Explanation:

We need to find the side lengths that form a right triangle ,

To find the pythagorean triplet ,we will use "Pythagorus theorem", which states that

H^2=B^2+P^2

As we have given that

A) 7 cm, 8 cm, 10 cm

We'll check for this

7^2+8^2\neq 10^2\\\\49+64\neq 100

so, it can't be the side of right triangle.

B) 15 m, 20 m, 25 m

We'll check for this

15^2+20^2=25^2\\\\225+400=625\\\\625=625

Hence, it is correct set of side lengths that form a right triangle.

On the other hand, C) and D) are not satisfying the pythagorus theorem,

because,

41^2\neq 40^2+10^2\\\\1681\neq 1600+100\\\\1681\neq 1700\\\\Similarly,\\\\3^2+5^2\neq 6^2\\\\9+25\neq 36\\\\34\neq 36

Hence, Option 'B' is correct.

Which ordered pair could you remove from the relation {(–2, –1), (–1, 1), (–1, 0), (0, 1), (1, 0)} so that it becomes a function
trapecia [35]
A polynomial expression can only be categorized into a function if and only if a single input can only have one and only output. This means that there should be no more than one dissimilar values of y for the same value of x. 

Evaluating the givens above, it can be observed that there are two -1's as an x-coordinate and it has two outputs, 0 and 1. Thus, we can remove either (-1,0) or (-1,1) for the relationship to become a function.
