Answer 2

• 
  `\underline{146}`

Explanation:

Plug in the value of x into the expression
`6x^2-4`.

- You will obtain this:
`6(5)^2-4`.

Then all you need to do is use the correct Order of operations to evaluate.

- For example, you need to square 5 first:
`6\cdot25-4`.

Then, you need to multiply:
`150-4`.

Then, you should subtract:
`146`
