Answer:

Step-by-step explanation:

$\frac{\sqrt{6} }{\sqrt{3} -\sqrt{2} }$

→ Multiply the numerator and denominator by $\sqrt{3} +\sqrt{2}$

$\frac{\sqrt{6} }{\sqrt{3} -\sqrt{2} }*\frac{\sqrt{3} +\sqrt{2} }{\sqrt{3} +\sqrt{2} }$

→ Simplify

$2\sqrt{3} +3\sqrt{2}$

One side of triangle twice the length of the shortest side and the 3rd side 14 more feet than length of shortest side, find dime

kifflom [539]

Let's say the sides are "a" first one, "b" second one and "c" the third one

ok, let's say the shortest is "a"
and let's say "b" is -> " twice the length of the shortest side"
so b = 2a

and let's say "c" is -> "3rd side 14 more feet than length of shortest side"
so c = a + 14

we know the perimeter ( sum of all sides ) is 154

 $\bf \begin{array}{llll}
a&b&c\\
&\downarrow&\downarrow \\
&2a&a+14\\
\downarrow &\downarrow &\downarrow \\
\end{array}\\
\ a+b+\ c=154\\\\
a+(2a)+(a+14)=154$

solve for "a"
