Solve by completing the square:

x² + 16x + 64 = 13 + 64
(x + 8)² = 77
x + 8 = +/- √77

x = - 8 +/- √77

OR

x = - 8 - √77, - 8 + √77

-43 - 4r = 3( 1 - 9r )
Karolina [17]

-43 - 4r = 3 - 27r

Add 27r to both sides. -43 - 4r + 27r = 3 -27r + 27r or -43 + 23r = 3

Add 43 to both sides. -43 + 43 +23r = 3 + 43 or 23r = 46.

Divide both sides by 23 to get r by itself. 23r / 23 = 46 / 23 or r = 2

r = 2
