I = PRT.....rearrange.....P = I / RT
P = 51 / (0.0425* 2).....I used 2 because 24 months = 2 yrs
P = 51 / 0.085
P = 600 <===
Slope of AB = 1/3 and slope of BC = -3 so these 2 lines are perpendicular
The same is true for all the other adjjacent pairs of lines.
Oppoitse lines are also paralllel ( slope of AB = 1/3 and slope of DC = 1/3) and other pair are both of slope -3.
So Its C
Answer:

Step-by-step explanation:
We need to find 1/4 of the area of a circle with a radius of 8
Let r be radius
Area of a circle = 
Substitute r with 8
Area of a circle = 
Now, to find 1/4 of the area, we can create an equation 
The answer is 
Hope this helps :)
Have a spectacular day!
I think the correct answer for this is
a cube of solid forms a puddle of liquid
but i am no sure it's correct or no
(x^2-1)(x^2+7) should be your answer
