Root of negative 2x plus 1 _ 3 = x
square root of negative 2x plus 1 _ 3 + 3 = x + 3
square root of negative 2x plus 1 = x + 3
square root of negative 2x plus 1 _ 1 = x + 3 _ 1
square root of negative 2 x = x + 2
(square root of negative 2 x)2 = (x _ 4)2
_2x = x2 _ 8x + 16
_2x + 2x = x2 + 8x + 16 + 2x
0 = x2 + 10x + 16
0 = (x + 2)(x + 8)
x + 2 = 0 x + 8 = 0
x + 2 _ 2 = 0 _ 2 x + 8 _ 8 = 0

List the sides of δrst in in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12°
