It is a vertical stretch by a factor of 5.
Answer:
1080 degrees
Step-by-step explanation:
A regular octagon has 135 degrees per interior angle. To find the sum, add 135 for each angle. There are 8 interior angles.
8*135 = 1,080
If she is making 6 costumes that need 3 7/9 yards each, the equation would be 6 x 3 7/9.
The answer to that equation would be 22 2/3.
How to get the answer:
3 x 6 = 18
7 x 6 = 42 (the seven is from the 7/9)
42/9 = 4 2/3
then add the eight teen and the 4 2/3 and you get 22 2/3.
First one. You can tell because it is linear. If you still do not understand watch a video on it.
