2x + 4 1/5 = 9
2x = 9 - 4 1/5
2x = 5 1/5
2x divided by 2 = x
5 1/5 divided by 2 = 13/5 (2 3/5, or 2.6)
x = 13/5 (2 3/5, or 2.6)
Answer:
D. 
Step-by-step explanation:
We can use a process of elimination in order to easily solve this.
The shape of 
will be two diagonal lines that meet at (0,0)
Will be an upside down parabola
Will be a line with a slope of -1.
This means that the answer must be D
-9 should be the answer because first you add three than take away six which is -9
I hope this helps! Just follow the instructions.
Short Answer A is the bad guy. <<<<
The line should read
The large square area = the 4 triangles + the inner square.
(a + b)^2 = c^2 + 4 ( 1/2 * ab)
(a + b)^2 = c^2 + 2 ab
