Answer:
Step-by-step explanation:
h^2=x^2+y^2, here x and y are equal so we can say
h^2=2x^2, we see that h=2(2^(1/2)) so
2x^2=8
x^2=4
x=2
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
