You asked:
Evaluate the expression: \({5}^{2} + 4 \cdot 5.5\)
MathBot Answer:
\[{5}^{2} + 4 \cdot 5.5 = 47\]
\[\begin{aligned}{5}^{2} + 4 \cdot 5.5& = 5^{2} + 4 \cdot \left(5 + \frac{5}{10}\right)\\& = 25 + 4 \cdot \left(5 + \frac{5}{10}\right)\\& = 25 + 4 \cdot \left(5 + \frac{1}{2}\right)\\& = 25 + 4 \cdot \frac{11}{2}\\& = 25 + 22\\& = 47\end{aligned}\]
