Answer:
A
Step-by-step explanation:
A because when you find the product you need to add
<h3><u>The correct answer is A and B.</u></h3>
Both A and B represent functions, as the same x value is not used twice.
However, with option C, the x value -2 is used twice, and thus it is not a function.
Answer:
Step-by-step explanation:
Expression is a polynomial when it contains variables, numbers and operators. Expression that contains fractional exponent is not a polynomial. Expression with variable in the denominator is not a polynomial.
It is a polynomial
It is not a polynomial because x is in the denominator
It is a polynomial
It is not a polynomial because it has fractional exponent

Answer: x = 155</h3>
Explanation:
Glue the two right triangles together to form one larger triangle.
The angle adjacent to the 60 degree angle is 180-60 = 120 degrees.
The angle adjacent to x is 180-x
The larger triangle has the interior angles of:
Those three angles add to 180 (which is true of any triangle)
35+120+180-x = 180
335-x = 180
-x = 180-335
-x = -155
x = 155
Or you can note that 35+120 = 155 which is the summation of the interior angles that aren't adjacent to exterior angle x (refer to the remote interior angle theorem, aka the exterior angle theorem).
