20^2 + 13.5^2 = c^2
            582.25 = c^2
          √582.25 = c
                 24.1 = c

\bf \textit{pythagorean theorem}\\\\
c^2=a^2+b^2\implies c=\sqrt{a^2+b^2}\qquad 
\begin{cases}
a=20\\
b=13.5
\end{cases}
\\\\\\
c=\sqrt{20^2+13.5^2}\implies c=\sqrt{582.25}\implies c\approx 24.12985702402730
\\\\\\
c\approx 24.1\impliedby \textit{rounded up}

Solve -52 = 4m for m
ZanzabumX [31]

Note the equal sign. What you do to one side, you do to the other.


Isolate the variable. Divide 4 from both sides


(-52)/4 = (4m)/4


m = -52/4


m = -13


-13 is your answer for m



hope this helps
