Answer 3

It looks like you want to add the following expressions together:

7кв + 9кв + 3кв

Assuming "кв" represents a variable or unit, and you want to add these terms together, you can simplify the expression by adding the coefficients (numbers in front of the "кв"):

7кв + 9кв + 3кв = (7 + 9 + 3)кв = 19кв

So, the simplified expression is 19кв.
