The Answer wouldn't be any other number but 9. I took this test and got it right.
Answer:
-4 <x< -2
Step-by-step explanation:
you need to plot the line between -4 and -2
for 2a, use the theorems of geometry and such to look at the area of the square as 16 squares total, then use the lengths and Sim/cos rule for the triangular area, then subtract and you have you shaded area.
