Answer:
Remember that regular octagon is a figure with eight sides, where all of them are equal. The image attached shows a regular octagon.
So, if we want to map the octagon on to itself using rotation, we need to rotate 90° clockwise, or make to moves of 45° each, that way the octagon would be as the original one because it has equal sides.
When you rotate the first 45°, you would have like an inclined octagon, so you need to rotate another 45° to get the same octagon as the original.
So, the minimum degree would be 45°, doing it twice.
Answer:
Step-by-step explanation:
Using the distance formula, and (-3, -3) as (x1, y1) and (-6, 1) as (x2, y2), we obtain sqrt(9+16) = sqrt(25) = 5.
So, the distance between the two points is 5 units.
(x – 3)(x – 15)
(x + 3)(x + 15)
(x – 3)(x + 15)

Step-by-step explanation:
Answer:
-28=7(x-7)
First expand the terms on the right side
That is
-28 = 7x - 49
Group like terms
7x = -28 + 49
7x = 21
Divide both sides by 7
7x/7 = 21 /7
x = 3
Hope this helps
Answer:
so x=3
Step-by-step explanation:
-28=7(x-7)
opening the brackets by multiplying
-28=7x-49
adding 49 on both sides
-28+49=7x-49+49
21=7x
dividing 7 on both sides
21/7=7x/7
x=3
i hope this will help you :)
