Which factors can be multiplied together to make the
trinomial 5x2 + 8x - 4? Select two options
0 (x+1)
(2x + 1)
(x+2)
(5x + 1)
(5x-2)

(5x−2) and (x+2)

Step-by-step explanation:

(5x-2)(x+2)

If you want to check your answer mulitply (5x-2)(x+2) and you get the same

trinomial 5x2 + 8x - 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
