Let its biggest angle be x:- If: 0.5x+0.5x+x+x = 360 degrees Then: 3x = 360 => x = 360/3 => x = 120 degrees Therefore inside angles are: 60+60+120+120 = 360 degrees
It can also be written as 3x + 7. The value of the expression will depend on the value of x.
3x=81 3x/3=81/3x=27

- If 3X - 1 = 11, what is the value of X^2 + X?
this is what you would: 4x+6=3x-1 -6 -6 ---- 4x=3x-7 -3x -3x ---- 1x=-7 ---- x=-7
What is ABCD? It is a quadrilateral, but what it is? What is 3x - 7? A side, a perimeter, or what else? Please, give me some additional information in order to be able to solve this problem.

There is not enough information provided in the question for it to be answerable.
8-3x = 128 -3x = 128-8 -3x = 120 x = -40

ANSWER 5 EXPLANATION The diagonals bisect each other so, AE=CE This implies that 3x+4+3x+4=38 6x+8=38 Group similar terms 6x=38-8 6x=30 x=5
