Enter the correct answer
OOB C

Answer 1

i)1

ii)-3

Explanation:

If x=-2

then to evaluate x+3 and x-1 we place the value of x in both its place:

i)x+3

= -2+3

=1

ii)x-1

=-2-1

=-3

Answer 2

For this case we must find the values of the expressions given taking into account that the variable "x" is equal to -2. (
`x = -2`)

Expression 1:

`x + 3 =\\-2 + 3 =`

Different signs are subtracted and the sign of the major is placed.

`-2 + 3 = 1`

Expression 2:

`x-1 =\\-2-1`

Equal signs are added and the same sign is placed.

`-2-1 = -3`

ANswer:

1,-3
