Answer 1

3(9 - h)
h = 5

3(9 - 5) =
3(4) =
12 <==

Answer 2

Answer:

Three times the difference of nine and a number.

Let the unknown number/variable be = h

The difference of 9 and the number is written as $9-h$

And three times this value (Three times the difference of nine and a number) is written as:

$3\times(9-h)$

Now we have to tell the value of the expression when h = 5 :

So, putting h=5 in the expression.

$3\times(9-5)$

$3\times4$

= 12

So, The value of the expression when h = 5 is 4.
