Answer:
72 cm
Step-by-step explanation:
You can solve this problem using the properties of the 45-45-90 right triangle. Assuming the 12 cm is a diagonal of the square, each side of the square can be modeled as x, and the diagonal will be x
.
This means
, so
.
Next, to find the area of the square you take the square of any of its sides. Since x is the length of one side, and
, you can square
to get the area. This is equal to
or 72 cm.
To find the distance traveled, we multiply the speed by the time. In this case, one person travels 60t miles in one direction, and the other person travels 50t miles in the other direction. So at any time t, the distance between the two people is 60t + 50t = 110t.
Given that the distance between them is 440 miles, we can solve for t with the following equation:
110t = 440
t = 4 hours

Step-by-step explanation:
I assume you are referencing y=mx+b. The equation gives you the slope of the line (m), and a coordinate (x, y). As well as b, which could be used for many things.
