A triangle has sides with lengths of 6 centimeters, 5 centimeters, and 3 centimeters. Is it a right triangle?

No

Step-by-step explanation:

A triangle with a side of five is only a perfect right triangle when it's in a 5,12,13 ratio.

Furthermore, to check, 5^2 is 25 and 3^2 is 9. 25+9 is 34, which doesn't not have a square root of 6.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

the answer to this question is 3/19
