If the snake is now 3 foot 9 inches, we can add up how many inches that is by converting feet to inches. 1 foot=12 inches, so 3 feet is 36 inches. We then add the 9 inches.
36+9= 45
Since the snake had already accomplished being 5 inches at birth, we can subtract 5 from 45.
This gives us 40.
Since the snake was born 4 years ago we divide 40 by 4.
(2x)2 > 3x2 is true the first two you can not have two x’s on the same side because where would you put them both when solving them the last one I’m not sure about
