A) 2 B) 5 C) 9 D) 10

Answer 1

The value of expression is 18.

Explanation:

The following information is missing in the question. The correct expression is
`4a+b - c`

We are given the following expression:

`4a+b - c`

We have to find the value of this expression when a = 5, b = 4 and c = 6.

Putting these values we get,

`4a+b - c\\=4(5)+4-6\\=20 + 4-6\\=18`

The value of expression is 18.
