Question

4) d = -(-2);6) k = +(-1).2) b = (+0,75);​

Answer 1

1)d=2
2)k= -1
3)b=+0,75

Answer 2

Let's evaluate the given expressions:

4. d = -(-2) To simplify this expression, we can remove the double negation: d = -(-2) = 2

5. k = +(-1) The positive sign in front of a negative number doesn't change its value. k = +(-1) = -1

6. b = (+0.75) There is no need for the positive sign in front of a positive number. b = +0.75 = 0.75

So, the values of the variables are: d = 2 k = -1 b = 0.75
