2X = (X+4)x8

Step-by-step explanation:

Let X = your number

per the problem twice the number (2X) is equal to the product of the sum of the number and four (x+4) and 8. Take all those parts and write the equation.

2X = (X+4) x 8

(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

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake
