The opposite angles of a quadrilateral are supplementary so you can set them equal to 180.

If there was more information given then i could find the exact values.

Hope this helps :)

Answer:

F is 0

Step-by-step explanation:

If you divide X on both sides to get X on one side, it will end with F = -2 + 2, which is 0

Answer:

For $(2x^2 + 8x - 8)$ , the group is CLOSED as it a polynomial.

Step-by-step explanation:

Here, the given polynomials are:

$P(x)=(5x^2+2x-6)\\Q(x)=(3x^2-6x+2)$

Now, a group G is said to be <u>CLOSED UNDER SUBTRACTION</u> if,

a and b are he elements of G ⇒ (a-b) is ALSO AN ELEMENT of G

Now, here:

$R(x) = P(x) - Q(x) = (5x^2+2x-6) - (3x^2-6x+2) = (2x^2 + 8x - 8)$

or, $R(x) = (2x^2 + 8x - 8)$

Also, R(x) is a POLYNOMIAL.

So, R(x) is an Element of group G.

So, the set G of polynomials.

Hence, for the polynomial $(2x^2 + 8x - 8)$ , it will be a polynomial the group is CLOSED.
