2x + 6 what is the value of this expression if x = 4? a) 2 b) 8 c) 14 d) 20

Hi,

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:

4. X = 14
