Answer 1

Answer: 4. 9 + 7n - 3

3. 62

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.
