Answer :
We begin with the first expression:
[tex]$$39.4 + (-7.2)$$[/tex]
Since adding a negative number is equivalent to subtracting, we have:
[tex]$$39.4 + (-7.2) = 39.4 - 7.2$$[/tex]
Evaluating the subtraction gives a result of approximately
[tex]$$32.199999999999996 \quad \text{(or simply } 32.2 \text{)}.$$[/tex]
Next, we move on to the second expression:
[tex]$$4.5 - 29.26$$[/tex]
Here, subtracting a larger number from a smaller one results in a negative value. The evaluation gives:
[tex]$$4.5 - 29.26 = -24.76.$$[/tex]
Thus, the final answers are:
[tex]$$39.4+(-7.2)=32.199999999999996$$[/tex]
[tex]$$4.5-29.26=-24.76.$$[/tex]
[tex]$$39.4 + (-7.2)$$[/tex]

[tex]$$39.4 + (-7.2) = 39.4 - 7.2$$[/tex]
