Question

Which two operations are needed to write the expression that represents "eight more than the product of a number and two"?

multiplication and subtraction
division and subtraction
multiplication and addition
division and addition

Answer 1

Answer: multiplication and addition

Explanation:

In mathematics we use addition(+) operation to show "sum", subtraction (-) to show "difference" , multiplication (×) operation to show "product" and divide (÷) to show "quotient".

Given mathematical statement : eight more than the product of a number and two

Here, we use addition(+) operation to show "more than" and multiplication (×) operation to show "product" .

Hence, the two operations are needed to write the expression that represents are : multiplication and addition

Answer 2

For this case we must represent the following expression algebraically:

"eight more than the product of a number and two"

Let "x" be the variable that represents the unknown number

We have to:

the product of a number and two is represented as:
`2x`

Then, the full expression will be:

`2x + 8`

Thus, we use multiplication and addition.
