Answer:

Two polygons are similar if their corresponding angles are congruent and the corresponding sides have a constant ratio (in other words, if they are proportional). Typically, problems with similar polygons ask for missing sides.

Answer:

-(√2)/2

Step-by-step explanation:

The expression evaluated at n=a gives the indeterminate form 0/0, so L'Hopital's rule can be used to find the limit. The second expression comes from differentiating numerator and denominator. Then the form with n=a is no longer indeterminate.

$\displaystyle\lim_{n\to a}{\frac{\sqrt{2n}-\sqrt{3n-a}}{\sqrt{n}-\sqrt{a}}}=\lim_{n\to a}{\frac{\frac{2}{2\sqrt{2n}}-\frac{3}{2\sqrt{3n-a}}}{\frac{1}{2\sqrt{n}}-0}}\\\\=\sqrt{a}\left(\frac{2}{\sqrt{2a}}-\frac{3}{\sqrt{3a-a}}}\right)=\boxed{-\frac{1}{\sqrt{2}}}$

What is 6/100 + 2/10

Andreyy89

Answer:

$\frac{26}{100}$

Step-by-step explanation:

$\frac{6}{100}$ can stay untouched, but $\frac{2}{10}$ has to be changed to $\frac{20}{100}$ . Now that they have they have the same denominator, you can add them. $\frac{6}{100} + \frac{20}{100} = \frac{26}{100}$ , which can be simplified, which is $\frac{13}{50}$ .
