Answer:
2
Step-by-step explanation:
Checkpoint A-> time being 1:00pm total miles driven being 120 and
checkpoint B-> time being 3:00pm and the total miles being 208
The distance between two checkpoint A and B is 208 - 120 = 88 miles
Now the time between the two checkpoints = 3.00 - 1.00 = 2 hours
We need to find car speed between the checkpoints
We know Distance = speed * time
Speed = 44 miles per hour
So we have two shapes that are exactly the same. All their sides are of equal length. The combined perimeter is 80 cm. Since they're identical, we can safely say that the perimeter of EACH figure is 40 cm. Let's work from that. Remember, the perimeter is the length of all the sides of a figure added together.
What's the first shape that comes into your mind when you think of "equal length sides"? Probably a square: a four-sided shape where all the sides are the same length. If this were a square, and its perimeter is 40 cm, then the length of each side is 1/4 of 40 cm, right? (Because there are 4 sides, and the perimeter is the length of all the sides combined.) This would make the length of each side 10 cm.
Let's check. If each side is 10 cm, and all 4 sides of the square are equal (which they are), the perimeter of each square is 40 cm. The combined perimeter is 40+40=80 cm. This works!
Answer: The figures are squares; each side is 10 centimeters long.
Parallel lines have the same slope, so the slope is 5
in point=slope form: (y-2)=5[(x-(-3)]
y-2=5(x+3)
in slope intercept form: y=5x+17
in standard form: 5x-y=-17
