Abcd is a quadrilateral inscribed in a circle, as shown below:
circle o is shown with a quadrilateral abcd inscribed inside it. angle a is labeled x plus 16. angle b is labeled x degrees. angle c is labeled 6x minus 4. angle d is labeled 2x plus 16.
what equation can be used to solve for angle d?
(2x + 16) + (6x − 4) = 90
(x + 16) − (x) = 90
(x + 16) + (2x + 16) = 180
(2x + 16) + (x) = 180
don't know this one

If i had 1234 apples and 1 banana what is the total amount

Someone answer this asap for the function f(x) and g(x) are both quadratic functions. f(x) = x² + 2x + 5 g(x) = x² + 2x - 1 which statement best describes the graph of g(x) compared to the graph of f(x)? a. the graph of g(x) is the graph of f(x) shifted down 1 units. b. the graph of g(x) is the graph of f(x) shifted down 6 units. c. the graph of g(x) is the graph of f(x) shifted to the right 1 unit. d. the graph of g(x) is the graph of f(x) shifted tothe right 6 units.

Pls yall i really need the answer fr fr
