Answer 1

Given:

The expression is

`-5x+4-x-1`

To find:

The terms, like terms, coefficients and constants.

Solution:

We have,

`-5x+4-x-1`

It can be written as

`=(-5x)+4+(-x)+(-1)`

So, terms are
`-5x,4,-x,-1`.

It two terms have same variable of same degree, then they are called like terms.

`-5x,-x` are likes terms because degree of variable is 1 and 4, -1 are like terms because degree of variable is 0.

In the product of a number and a variable, the number is called coefficient.

Variable terms are
`-5x,-x`. So, coefficients are -5 and -1.

Constant terms are free from variable. So, constant terms are 4 and -1.

Terms:
`-5x,4,-x,-1`;

Like terms:
`-5x, -x;4, -1`;

Coefficients: -5, -1;

Constants: 4, -1

Therefore, the correct option is c.
