Answer 2

Answer:

The variable expression is given by:

                    86*d

Step-by-step explanation:

We are asked to convert the given phrase into a variable expression.

We are asked to use the letter "d" to denote the variable and "*" sign is used in place of the product or multiplication.

The phrase is:

   ...The product of 86 and the depth of the river...

Let d denote the depth of the river.

Hence, the conversion of the given expression into the  variable form we have:    

                     86*d
