Answer:

x = 13

Step-by-step explanation:

a^{2} +b^2 = c^2\\12^2 + 5^2 = c^2\\144 + 25 = c^2\\169 = c^2\\

Take the square root of both sides

\sqrt{169} = \sqrt{c^2} \\13 = c

Answer:

14

Step-by-step explanation:

To get the answer, add the whole numbers together and then add the fractions together:

9 + 4 = 13

(You can even stop here because 14 is the closest to 13)

Now, add the fractions:

\frac{2}{3}+\frac{1}{5}

To add fractions you have to have a common denominator. To find the common denominator multiply 3 by 5, and 5 by 3. Like this:

(\frac{5}{5})\frac{2}{3}  + \frac{1}{5} (\frac{3}{3} )

Simplify:

\frac{10}{15} +\frac{3}{15}              Distribute everything from above

\frac{13}{15}                      Add

So, the whole fraction will look like this 13\frac{13}{15}. This is closest to 14.

Hope this helps!! Ask questions if you need!
