Mario says that the expression
has four terms: 4, 3, n, and 2. Mario is incorrect
<em><u>Solution:</u></em>
Given that the expression is:

Given that, Mario says that the above expression has four terms
But Mraio is incorrect
Because the given expression has two terms only
4 is one of the term
is another term
So there are totally 2 terms only
A term can be a signed number, a variable, or a constant multiplied by a variable or variables
Here 3 is a constant multiplied by 
So,
is one term
Each term in an algebraic expression is separated by a + sign or - sign
Thus there are two terms in mario expression

Answer:
(D) 
Step-by-step Explanation:
Assuming that the equation
= p, we can convert the equation into this.

We can convert
into 9p because
× 9 = 
Now we simplify this equation.
We can subtract 9p from both sides of the equation.

Re-ordering the equation gets us:

So, (D)
is equivalent to the original expression of
