What's a regular heptagon? "Hept-" means seven, so a "heptagon" is a seven-sided shape. A "regular" figure's sides are all the same length. So, each of the 7 sides are the same length.
Remember, perimeter is the sum of the lengths of all the sides in a polygon. We know one side measures three inches, so each of the others must also measure 3 inches. 3+3+3+3+3+3+3=3*7=21 inches.
Answer: 21 inches
33-7r = 3(6-4r)
33 - 7r = 18 - 12r
33 -7r + 7r = 18 - 12r + 7r
33 = 18 - 5r
33 - 18 = 18 - 5r - 18
15/5 = 5r/5
3 = r
r = 3
D(t)=100t/4=25t
d(5min)=25*5=125ft
d(16min)=25*16=400ft
The others are not ordered pairs of d(t)
The correct answer is -The position changes, and the angles remain congruent. or C.
The size does not change because the shape is only moving to new coordinates not growing or shrinking.
This means the shape also does not change.
When you translate a shape in geometry it means you are changing the position. But the shape will remain the same, meaning the angles remain congruent.
B Bc it’s a right triangle meaning it’s 90 degrees so 90-10 is 80 and 80 divided by 2 is 40
