Is “Hazel Ari McKinney” a good name for when I have a kid

yes

Step-by-step explanation:

its a pretty name

Yes, as long as you like it. (For what it's worth, I think that's a pretty name, and I'm glad you don't want to name a kid something horrendous like Blanket or Apple.)

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
