Textbook Problem

In Exercises 33 to 36, find the value of the indicated variable for each given formula. w ,  if  S = 2 l w + 2 w h + 2 l h ,   S = 148 , l = 5 ,  and  h = 6

To determine

To find:

The value of the indicated variable w for the given formula.

Explanation

Concept for evaluating the expression:

1) In an algebraic expression, letters can stand for numbers.

2) Substitute a specific value for each variable.

3) Then perform the operations.

Calculation:

Given:

Formula: S=2lw+2wh+2lh

Substitute S=148,l=5, and h=6 in the given formula, we get

S=2lw+2wh+2lh148=25w+2wȬ
