Acompany that sells cellular phones has a cost of 4x + 10 dollars and a revenue of x2+5x+6 dollars, where x represents the number of cell phones sold per week. if profit = revenue - cost, find the company's profit.

a) x^2+x−4

b) x^2+2x−4

c) x^2−x+4

d.) x^2−2x+4

(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
