A triangle has side lengths of 7.1, 12.6, and b. Which of the following CANNOT be b? (A) 5.7 (B) 7.5 (C) 10.1 (D) 18.5 (E) 19.9
GuDViN [60]

-- When the 7.1 and 12.6 sides both point in exactly the same direction,
their open ends are 5.5 apart.  So the missing side must be greater than 5.5 . 
All of the choices are greater than 5.5 , so we haven't found it yet.

-- When the 7.1 and 12.6 point in opposite directions, their open ends are
19.7 apart.  So the missing side can't be greater than 19.7, otherwise the
two sides we know couldn't reach between its ends.  <u>Choice 'E'</u> is greater
than 19.9, so it can't be the missing side.

I need to graduate please.<br>Which expression is a perfect cube?<br> x^8<br> y^24<br> m^26<br> s^64
myrzilka [38]
Remember
(a^b)^c=a^{bc}

note that if a^3 is a perfect cube then (a^3)^c is also a perfect cube when c is an integer

(a^3)^c=a^{3c}
so if a number is a perfect cube then the power must be divisible by 3

8 is not divisible by 3
24 is divisible by 3
26 is not divisibley by 3
64 is not divisible by 3

the perfect cube is y^24
