12. The graph corresponds to Mr. Davis's shopping trip to a mall by car. (1 point) What most likely happened between 6:30 p. m. and 7:00 p. m.?
A.) Mr. Davis was looking for a parking space.
B.) Mr. Davis got tired and went home.
C.) Mr. Davis was at the mall shopping.
D.) Mr. Davis backed out of his driveway.

the answer will be b x² +x-1

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
