Answer:
Step-by-step explanation:
area=length×width
=(2x+3)(3x-5)
Area=6x²-10x+9x-15
=6x²-x-15
Step-by-step explanation:
-3 (4a-5b)
=-3×4a -(-3×5b)
=-12a+15b
Just to make it clear here is the graph. I was gone so long, it destroyed my answer.
Very briefly
8/30 * 360 = 96 which is the angle for the cloudy days.
12/30 * 360 = 144 which is the angle for the sunny days
10/30 * 360 = 120 which is the angle for the rainy days.
The graph shows how this would be plotted. It's not really well done, but it is there.
