4(x-3y) what does this equal

4x-12y supongo que sí es la respuesta que buscas

4x - 12y

Step-by-step explanation:

In order to expand brackets you have to multiply everything in the brackets by what is outside the brackets

Therefore:

4 x x = 4x

4 x - 3y = - 12y

Put this together and you end up with 4x - 12y

Hope this helps

(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
