Because the symbol is greater than and equal to Y it would be a solid line with the blue are to the right of the red line
the correct graph would be B
There is actually a cool trick to this. When you see a and 2a, in this case 6 and 12, then the small triangle is a 60-30-90 triangle. The remaining side is
.
This value rounds down to 10, and yep, you guessed it, another 30-60-90.
This time, x =
.
This is a very difficult problem and requires knowledge of the special triangles. Hope this helps!
I hope this helps you
l=x+2
w=2x-5
(x+2)(2x-5)=56
2x^2-x-10=56
2x^2-x-66=0
2x +11
x -6
(2x+11)(x-6)=0
x=6
