The correct answer is C because the problem showed ( x + 20 ) and ( x + 8 ) two times in the problem. That explains why there is a two outside of the parentheses.
Hope I helped! :)
Perpendicular lines, C is the answer.
To solve this equation, Simplify the first and then the second.
First will be solved like: -y=3x+3, y=-3x-3. The second will be simplified as: 9y=3x+2, y=1/3x+2/9. Then you divide by 3.t.
I can't understand what you wanted with the second question (or if that is even a question), but the answer to the first one is 42.
