Answer:
9 units
Step-by-step explanation:
You can split the polygon into two right triangles and a rectangle. The two right triangles each equal to 1.5 and the rectangle is equal to 6 so 6+1.5+1.5=9
(x + 8)(x - 6)
to factorise consider the factors of - 48 which sum to + 2
These are + 8 and - 6 thus
x² + 2x - 48 = (x + 8)(x - 6)
