Answer: 4. 9 + 7n - 3

3. 62

Step-by-step explanation:

Given statement: nine more than the product of seven and a number decreased by three

Let n be the number.

Then, required expression: $9+7n-3$

Correct option is 4.

When n= 8 ,

The value of expression = $9+7(8)-3= 9+56-3 =62$

Hence, value of the expression when n = 8 is 62.

Correct option is 3.
