Answer:
Step-by-step explanation:
<-- Given
<-- Multiply by the conjugate of the denominator as a factor of 1
<-- Use the Distributive Property and FOIL
<-- Rewrite 
as 
<-- Rewrite in 
form
1st let's calculate r the common ratio:
r = (-20)/4 = (100/-20) = -5
Value of nth term = a₁.rⁿ⁻¹, where a₁= 1st term and n, the rank
Value of nth term = 4r⁽⁷⁻¹⁾ = 4.(-5)⁶
Value of nth term = 62,500
Answer: 
Explanation:
The area of a triangle A can be calculated as A=(height)x(base)/2
We know the height is 6x.
We know 
So the equation becomes (using |AC| as the base length):
The base is
A line that is parallel to y = 3, a horizontal line, would also be a horizontal line.
The only option that is a horizontal line passing through (0,6) is y = 6.
