Chapter SH, Problem 9.1.22EP

To determine

Evaluate the expression

  $5p-m^2$

Answer to Problem 9.1.22EP

The evaluation of $5p-m^2$ is $-29$

Explanation of Solution

Given:

Expression: $5p-m^2$

  $\begin{array}{l}m=3\\ n=2\\ p=-4\end{array}$

Calculation:

Evaluate the expression when $5p-m^2$

First substitute the expression, $m=3,p=-4$ in $5p-m^2$

So the expression can be written as follows,

  $5p-m^2=5\left(-4\right)-3^2=-20-9$

So,

  $5p-m^2=-29$

Conclusion:

Hence, the value of $5p-m^2$ is $-29$ .
