Now,I would get rid of the parenthesis,also remember a double negative is a positive.
6x+ 6y-x+7y
Now add or subtract like terms.
5x+13y
You can check this by put x as 1 and y as 2, and putting it in to both equation. (I do this, you don't have to)
3(2 +4) - (1- 14)
18+ 13= 31
5 + 26= 31
So it would be 5x+13y.

Find the value of x. Polygon angle sums
pav-90 [236]

Answer:

x = 50

Step-by-step explanation:

In a polygon, the angles add up to 360°:

x + 10 + 2x + 3x + x = 360

7x + 10 = 360

7x = 350

x = 50

Can you double a square with a straightedge and a compass?
sergejj [24]
I'd say yes.  If you use the diagonal as a reference.  Take the square and set your compass to the width of the diameter of the square.  Now put it on the page and mark a point.  Put the point of the compass on that mark and make another mark.  Now you can connect the two marks with the straight edge and you have a line that, if you made a square with sides that long, it'd have 2x the area of the first one.  That's because the diagonal is the square root of 2 larger than one side.  Square the square root of 2 and you've got 2.  You lust need to make a perpendicular line to the first one to get the box going.
