Answer for Blank 1:

Answer 1

3
this is because

`x^(3)y`

`x^(2)`
and
y
are all separate variables (also
`x^(3) y` combines into one variable)

Answer 2

3 Variables are
`x^3y, x^2, y`

Explanation:

Given : Expression
`3x^3y+5x^2+y+9`

To find : How many variable terms are in the expression?

Solution :

In the expression a letter represents a variable.

In
`3x^3y` the variable is
`x^3y`

In
`5x^2` the variable is
`x^2`

In
`y` the variable is
`y`

In
`9` there is no variable.

i.e. In the expression
`3x^3y+5x^2+y+9` there are three variables.

Variables are
`x^3y, x^2, y`
