Question

Answer 1

Ответ:

5,1

1,1+1+3=2,1+3=5,1

Answer 2

To evaluate the expression (х+1)-(-3) when х=1.1, we simply substitute the value of х into the expression:

(1.1 + 1) - (-3)

Now, let's solve it step by step:

1.1 + 1 = 2.1

Now, we have:

2.1 - (-3)

To subtract a negative number, we can change the sign of the negative number and then add:

2.1 + 3 = 5.1

So, the result of the expression (х+1)-(-3) when х=1.1 is 5.1.
