Answer:

Yes because 5^2 + 12^2 = 13^2

Step-by-step explanation:

We can check using the Pythagorean theorem

a^2 + b^2 = c^2

5^2 + 12^2 = 13^2

25+ 144= 169

169 = 169

Answer:

  D.  Yes, because 5² +12² = 13²

Step-by-step explanation:

To determine if a triple of three numbers will form a right triangle, see if they satisfy the Pythagorean theorem. If they do, the sum of the squares of the smaller two numbers will equal the square of the largest.

Here, we have ...

  5² + 12² ?? 13²

  25 +144 ?? 169

  169 = 169 . . . . . . these side lengths will form a right triangle

_____

<em>Additional comment</em>

Three integer numbers like these that will satisfy the Pythagorean theorem are called a "Pythagorean triple." A few such triples that are commonly seen in algebra and trig problems are ...

  (3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17), (9, 40, 41)

It is worthwhile to remember a few of these, as you will see them again.

G(n)=n^3+n<br> g(-3)<br> help!
Svetradugi [14.3K]
The question is simply asking you to evaluate the function for an input value of -3. Meaning we plug in -3 for all cases of n. (-3)^3 + (-3). This gives us -27 -3 which is -30. So g(-3)= -30
