What is 5√28 + √63 in simplest radical form? PLEASE HELP ME!

1 answer:

8 0

$\bf 5\sqrt{28}+\sqrt{63}~~ \begin{cases} 28=2\cdot 2\cdot 7\\ \qquad 2^2\cdot 7\\ 63=3\cdot 3\cdot 7\\ \qquad 3^2\cdot 7 \end{cases}\implies 5\sqrt{2^2\cdot 7}+\sqrt{3^2\cdot 7} \\\\\\ 10\sqrt{7}+3\sqrt{7}\implies \stackrel{\textit{adding like-terms}}{13\sqrt{7}}$

Use the slope formula to find the slope of the line through the points (2,10) and (10,−8).

Salsk061 [2.6K]

The slope formula is the changes of two y-values over/to the changes of two x-values.

$\large \boxed{m = \frac{y_2 - y_1}{x_2 - x_1} }$

Substitute two given points in the formula to find the slope. The m-term represents the slope from y = mx+b.

$\large{m = \frac{10 - ( - 8)}{2 - 10} } \\ \large{m = \frac{10 + 8}{ - 8} } \\ \large{ m = \frac{18} { - 8} \longrightarrow \frac{9}{ - 4} } \\ \large \boxed{m = - \frac{9}{4} }$

Answer

The slope is -9/4.

Hope this helps and let me know if you have any doubts!
