Question

Write a variable expression to represent each of the ff.1. The sum of a number and twelve.2. The diffrence bettween a number and eight.3. Three time a number4. A number squared plus five 5. A number divide by two plus seven

Answer 1

1). x + 12

2). x - 8

3). 3x

4).

`4).\text{ x}^2\text{ + 5}`

5).

`(x)/(2)+7`

Step-by-step explanation

Let x represent the number

1). The sum of a number and twelve = x + 12

2). The difference between a number and eight = x - 8

3). Three time a number = 3x

4). A number squared plus five

`x^2\text{ + 5}`

5). A number divide by two plus seven

`(x)/(2)+\text{ 7}`

Hence, those are the variable expressions.
