Will mark ! a video game club charges a fixed annual membership fee of $18 and $3 per video game rented. let f(n) represent the total annual cost of renting n video games. which of the following functions best represents the relationship between f(n) and n if the membership was increased by $20 the next year? answer choices: f(n) = 18n + 38 f(n) = 38n + 18 f(n) = 3n + 38 f(n) = 3n + 18

honestly bro aint no one got time to answer these dumb question just do it p***y

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
