Answer:
There are some unknown characters in the answer list, so am not certain which letter. However, the expansion of (x^2 + y)^2 is:
 x^4 + 2yx^2 + y^2.
Note: Am using the carrot - shift 6 - ^ to denote "to the power of".
Step-by-step explanation:
(x^2 + y)^2 = (x^2 + y) * (x^2 + y)
                   = (x^2 * x^2) + (y*x^2) + (y*x^2) + (y * y)
                   = x^4 + 2yx^2 + y^2
In words the answer is: x to the 4th plus 2 yx squared plus y squared.

Answer:
The slope of the line is 
Step-by-step explanation:
For any line  , a line that is perpendicular to it is
, a line that is perpendicular to it is  .
. 
Therefore the slope of the perpendicular line is  .
.
For our case  therefore the slope of the prependicular is the reciprocal of
 therefore the slope of the prependicular is the reciprocal of  multiplied by
 multiplied by
