Question

Look at this expression, and complete the statements.

3x + 2(x + 2) + 4
In the first term, 3 is
In the second term, (x + 2) is
In the last term, 4 is

Answer 1

Answer: In the first term, 3 is a coefficient

In the second term, (x + 2) is a factor

In the last term, 4 is a constant

Explanation:

The 3 in the first term is multiplied by a variable, x. So it is a coefficient.

The (x + 2) in the second term is multiplied by 2. So, it is a factor.

The 4 in the last term is not multiplied by anything. It is a fixed value, so it is a constant.

Answer 2

`3 \to` Coefficient of x

`(x+2)\to` Variable

`4 \to` Constant

Explanation:

Given

`3x + 2(x +2) + 4`

Required

Complete the statements

In 3x, x is the variable; so:

`3 \to` Coefficient of x

In 2(x + 2), 2 is the variable so:

`(x+2)\to` Variable

4 stands alone. So, it is a constant

`4 \to` Constant
