QUICK ANSWER
A quadrilateral with exactly one pair of opposite parallel sides is called a trapezoid. As with all quadrilaterals, the sum of the interior angles of a trapezoid is always equal to 360 degrees
Problem

Solution
For this case we want to find the domain for this case and we can analyze the denominator on this case because cannot be equal to 0, so we can set up this:

If we factorize we got:
(X-3)(x+2)=0
So then we have X=3 and X=-2
With these results we can conclude that the value of x cannot be 3 or -2 because then the function will be not defined
And the best solution is:
A. all real numbers except -2 and 3
ans is 25
Step-by-step explanation:
12(10-5)-40+(4+1)
=12 of 5 - 40 + 5
= 60 - 40 +5
=60 +5 - 40
=65-40
=25
According to the question, the region is bounded by the curve with the given data as 
To compute the volume of the solid, use the disk method. The given object is rotated along the horizontal axis with the disk cross sectional area and the volume can be written as:

As per question, when x = 1 then the value of y is: y = 1
Now, substituting calculated values in the expression:

Substitute the value of the variable 'x':
Therefore, the expression can be written as:
