Heres an ez question for yall
SSSSS [86.1K]

Answer:  Choice B

\left\{ \ 3, 5, \sqrt{34} \ \right\}

=========================================================

Explanation:

We'll be using the converse of the pythagorean theorem.

If we had a triangle with sides a,b,c and a^2+b^2 = c^2 was true, then we have a right triangle. Note: c is always the longest side

For the first answer choice we have: a = 5, b = 8, c = 12

Then,

a^2+b^2 = c^2\\\\5^2+8^2 = 12^2\\\\25+64 = 144\\\\89 = 144\\\\

which is false. This shows that we do not have a right triangle with sides 5,8,12. This rules out choice A. Choice C is a similar story.

Choice B on the other hand works because

a^2+b^2 = c^2\\\\3^2+5^2 = (\sqrt{34})^2\\\\9+25 = 34\\\\34 = 34\\\\

We have a true statement at the end, which confirms <u>choice B</u> is a right triangle.

F(x) = square root of x+9 ; g(x) = 8x - 13<br> Find f(g(x))
ryzh [129]

Answer:

\sqrt{8x-4}

Step-by-step explanation:

Substitute x = g(x) into f(x) , that is

f(g(x))

= f(8x - 13)

= \sqrt{8x-13+9}

= \sqrt{8x-4}
