Answer:
The correct answer is neither. 
Step-by-step explanation:
To find the relationship between the lines, find the slope of each. You can do this by using the slope formula. 
m(slope) = (y2 - y1)/(x2 - x1)
m = (4 - 1)/(4 - -8)
m = 3/12
m = 1/4
Now do so for the second line. 
m(slope) = (y2 - y1)/(x2 - x1)
m = (-3 - -7)/(9 - -9)
m = 4/18
m = 2/9
Since they are not the same and not opposite/reciprocal, then we know they are neither parallel nor perpendicular.

Answer:
Step-by-step explanation:
Area of rectangle = length * width
  = (3x + 2)(4x + 10)
   = 3x *(4x + 10) + 2*(4x + 10)
  = 3x *4x + 3x *10 + 2*4x + 2*10
  = 12x² + <u>30x + 8x</u> + 20   {Combine like terms}
   = 12x² + 38x + 20
