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
So remember that the area of a trapezoid is , with b = bases and h = height. Before we can do the equation, however, we have to find the height. Using the right triangle, we can use the pythagorean theorem, which is
.
Since we know that the hypotenuse is 13 and one of the legs is 12, we can solve for the other leg. Our equation will look like this:
Firstly, solve the exponents:
Next, subtract 144 on both sides:
Next, square root both sides, and your height will be: x = 5
Now that we know both the height, 5, and the bases, 30 and 40, we can solve for the area of the trapezoid. Our equation will look like this:
Firstly, combine everything on the numerator:
Next, divide the fraction:
Next, multiply, and your answer will be A = 175 un^2.
