Answer:
Step-by-step explanation:
4(0) + 3y=12
4x0=0
0+3y=12
3 x 4=12
y=4
Slope = difference in y / difference in x
slope = 5 - 0 / 4 - 10
slope = 5 / -6
slope = -.83333
Answer: 464 km²
Step-by-step explanation:
We will break this shape up into two parts. You can do this in two different ways, see attached for how I did it.
Area of a rectangle is A = L * W;
40 km * 9 km = 360 km²
13km * 8 km = 104 km²
Now we will add them together for total area:
360 km² + 104 km² = 464 km²
The answer is forty inches
