Answer:
A. (x + 2)^2 = 31.
Step-by-step explanation:
x^2 + 4x = 27
x^2 + 4x - 27 = 0
A. (x + 2)^2 = 31
x^2 + 4x + 4 - 31 = 0
x^2 + 4x - 27 = 0
This option corresponds to the given equation, so it is correct.
B. (x + 2)^2 = 43
x^2 + 4x + 4 - 43 = 0
x^2 + 4x - 39 = 0
This does not correspond to the equation.
C. (x + 4)^2 = 31
x^2 + 8x + 16 - 31 = 0
x^2 + 8x - 15 = 0
This does not correspond to the equation.
D. (x+4)^2 = 43
x^2 + 8x + 16 - 43 = 0
x^2 + 8x - 27 = 0
This does not correspond to the equation.
So, your answer is A. (x + 2)^2 = 31.

Answer:
(-1,-9)
Step-by-step explanation:
(5,-2)
-5 -4 -3 -2 <em><u>-1</u></em> 0 1 2 3 4 <u>5</u>
starting at 5, move 6 units to the left, your new x-coordinate is -1
<u>-2</u>
-3
-4
-5
-6
-7
-8
<em><u>-9</u></em>
starting at -2, move 7 units down, your new y-coordinate is -9
The new point after the translation will be (-1,-9)
It should be A.. its the only choice where i see -1
