What is the value of this expression if x = 4?
A) 2
B) 8
C) 14
D) 20

Answer 1

`\sf \: c) \: 14`

Explanation:

The expression is,

→ 2x + 6

Given information,

→ x = 4

Now the value of expression is,

→ 2x + 6

→ 2(4) + 6

→ (2 × 4) + 6

→ 8 + 6

→ 14 ==> [option (c)]

Hence, the required value is 14.

Answer 2

Hi,

Answer: C) 14

My work: This work can be easily achieved by taking your x value and plugging it into x in your problem. Next step would be to simply 2(4)+6. When done you get,your answer 14, which is C. This problem can be an easily 4 step problem as shown below!

Numerical work:

1. 2x +6. X=4

Plug in:

2. 2(4) +6

Multiply:

3. 8 + 6

Simplify:
