which expression represents the following situation? Multiply the sum of a number and 3 by the difference of 8 and a number

(x + 3) * (8-y)

Step-by-step explanation:

The first step to solve this question is interpreting it.

The first keyword is multiply

It means that we are going to multiply two terms.

Sum of a number and 3.

We do not know the number, so i am going to call it x.

So (x + 3)

The difference of 8 and a number

Another number that we do not know, and it does not say that these numbers are equal, so i am going to call this number y.

So (8-y)

Multiplying

(x + 3) * (8-y)

The expression would be (x + 3) (x - 8) and if we multiplied those together we would get x^2 - 5x - 24

Step-by-step explanation:

In order to find these, first put the sum of a number and 3.

(x + 3)

Then put the difference of that number and 8.

(x - 8)

The last step is multiplying them if you need to.
