Let a, b and c be 3 numbers whose Greatest Common Factor is 13.
This means that all a, b, and c are multiples of 13, and the three of them have no other common factor (except1)
So we can construct a, b and c as follows:
a=13*2*3, b=13*2*5, c = 13*7
a=78, b=130, c=91
Answer: {78, 130, 91}
Well, if a number has more than two factors then it is Composite. But if the number has only two factors the it is Prime.
So the number 212 is a Composite number.
plus all the numbers use the number answer/1 x100% and you will get your answer
Y>3 is the correct answer because more than 3 inches of rain fell.
I believe the perimeter is 232. Since it's a regular polygon that means all the sides are equal so you take the two expressions on the sides of the polygon and set them equal to each other. Now you know that x=22 so you take that value and substitute it into one of the expressions to get the side length (x+7➡️22+7=29) now we know that each side length is 29. Since there are 8 sides you multiply 29 by 8 and get 232. Hope this helped!
