2, 3, 5. I just solved them and they look equivalent.
4(2x +5) = (8x + 20)
8x =20 is an equivalent expression
So all you have to do is look at were the number is is it is in the first spot it is in the tenths place value, second spot hundredth and so
To calculate distance between two points we use the distance formula sqrt((x2−x1)^2+(y2−y1)^2).
To start, we find the square of the distance between x1 and x2 and y1 and y2. The distance between x1 and x2, or 1 and 3, is 2. The distance between y1 and y2, or 3 and -4, is 7.
Now we square 2 and 7 and add them together to get 4 + 49 = 53.
The last thing we do to find the distance is take the square root of 53. 53 is not a perfect square and is also a prime number so our answer in simplest form is still sqrt53.<span />
