Answer is x+9=11
6+x=9
x=3
15=x+12
x=3
7+x=10
x=3
x+9=11
x=2
So x+9=11 has a different x value than the rest of the equations. So it doesn't belong with the other three.
The probability of it landing in the shaded area is 4/10, or 2/5 simplified, or 40%. Hope this helps! <3
2(5x^2+2x)+2(3x^2)
10x^2+4x+6x^2
16x^2+4x
D is the correct answer.
