The correct answer is 3x+90=180
<em>Because you add the 2x and the x and you get 3x then there is a 90 degree angles so you add that and =180</em>
<em>Once you put it in the equation you can subtract 90 from 180 and you get 90 which you then divided by 3x and x equals 30</em>

9x-3xy
Factor out 3x from both terms.
3x(3-y)
answer: 3x(3-y)
4 + 10 = 2 x 2 + 2 x 5 = 2 x (2 + 5)
