Step-by-step explanation
Combine like terms (6x and 3x, 2 and 7)
Answer:
x = 9
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
50° is an exterior angle of the triangle, thus
38 + 4x - 24 = 50 , that is
14 + 4x = 50 ( subtract 14 from both sides )
4x = 36 ( divide both sides by 4 )
x = 9
One expression could be three x to the power of two. Let me know if that's right :)
There's a site called m.a.t.h.w.a.y, and you can type in those functions in order to get the graph ;)
The answer is B (Sorry for the bad handwriting.)
