Answer:
C
Step-by-step explanation:
Base area = n^2
V = (base area * height)/3 = (n^2 *(n-1)/3 = 1/3n^2(n-1)
Here is ur perfect answer
Example. Convert y=54x+5 y = 5 4 x + 5 , graphed on the right, to standard form. The only fraction is $$ \frac { 5}{ \red 4} $$ so you can multiply everything by 4. Solve for the y-intercept (or "b" in the slope interceptequation) which is 20 in this example.
Point slope form is
(y - y1) = m(x-x1)
m is a slope, m=1/3.
x1 = 3,
y1 = 2
(y-2) = (1/3)(x-3)
