Question

Multiple the sum of a number and 3 by the difference of 8 and the number

Answer 1

Answer:

-n^2 - 5n + 24

Step-by-step explanation:

Let the number be n.

Then the sum of that number and 3 is n+3.

The difference of 8 and the number is 8 - n.

Then we get the expression (n + 3)(8 - n).

Performing the indicated multiplication, we get:

8n - n^2 + 24 - 3n, or

-n^2 - 5n + 24

Nothing more can be done, as this is not an equation, but rather an expression.
