5
Step-by-step explanation:
There is one line of symmetry for each side of the pentagon.
Divide total distance by total time:
30 feet / 2 seconds = 15 feet per second
Answer: 15 feet per second
Using cross multiplication,
30 x 14 = 20 x w
so
w = 420/20
w = 21
Answer: The Circumference of a circle has the greatest measure.
Step-by-step explanation: A chord connects two points on a circle that are shorter than the diameter. The diameter is the measure across the widest part of the circle.
Circumference is the perimeter of the circle, the distance all the way around. It is π × diameter-- a bit more than 3 times the length of the diameter.
The first one is multiplying x^4 by itself 4 times and the second one is multiplying x^4 by 4 3 times
