Chapter 6.7, Problem 26E

To determine

To evaluate : the expression $6xz$ when $x=3$ and $z=4$ .

Answer to Problem 26E

The value of the expression is $72$ .

Explanation of Solution

Given information :

Consider, the expression provided in the question,

  $6xz$

The values of x and z are $x=3$ and $z=4$ .

Calculation :

To evaluate the expression, it is needed to substitute $3$ for $x$ and $4$ for $z$ in expression $6xz$

Therefore, the value of the expression is obtained as:

  $\begin{array}{l}6xz=6\left(3\right)\left(4\right)\\ 6xz=18\left(4\right)\\ 6xz=72\end{array}$

Hence,

The value of the expression is $72$ .
