Which expression is equivalent to 2x−4+4(3x−2)2x−4+4(3x−2) ?

a) 4(5x−2)4(5x−2)

b) 14x−614x−6

c) 2(7x−6)2(7x−6)

d) 8x(3x−6)

(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

d 600 because 15*10*2=300

300+300=600
