Therefore, the width of the garden bed must be less than or equal to 4 feet.
Given:
The expression is 
.
To find:
The position of parentheses inserted in the expression to get the value 19
Step-by-step explanation:

Now,
There are more ways to apply the parenthesis, but we do not get 19.
And many more possibilities.
Therefore, the expression after inserting the parentheses is 
.
Answer:
B
Step-by-step explanation:
