Hello from MrBillDoesMath!
Answer:
x = 8, x = -4
Discussion:
5 | x - 2| = 30 => divide both sides by 5
|x -2| = 30/5 = 6 => |x-2| = 6
(x-2) = 6 => x = 2 +6
x = 8
or
(x-2) = -6 => x = 2 + -6
x = -4
Thank you,

The initial length of the blue ribbon = 1.6 meters
Step-by-step explanation:
Here, according to the question:
The initial length of orange ribbon = 2 meters
Let us assume the initial length of blue ribbon = S meters
Now, the length of blue ribbon = (4/5) times the length of orange ribbon
x Length of Orange ribbon

or S = 1.6 meters
Hence, the initial length of the blue ribbon is 1.6 meters.

Answer:
u forgot pic lol
Step-by-step explanation:
Y² + 2 y - 2x - 3 = 0
x + 3 = y² + 2 y
2 x + 3 = y² + 2 x + 1 - 1
2 x + 3 = ( y + 1 )² - 1
2 x + 3 + 1 = ( y + 1 )²
Answer:
2 ( x + 2 ) = ( y + 1 )²
