N^4 - 1 = (n^2 - 1)(n^2 + 1)
= (n + 1)(n - 1)(n^2 + 1)
X = 60°
Because the square in the corner tells you that it is 90° (right angle)
So your equation to solve for x would be...
x + 30 = 90
Now you need to isolate the x.
Subtract both sides by 30.
x + 0 = 90 - 30
x = 60
Step-by-step explanation:
Given
(x1 , y1) = ( 0 , 3)
(x2 , y2) = ( 1 , 8)
Now
Gradient =

B
It is the last one because if you go 3 left you have to change the sign to a positive (but it is still a negative) and the 2 remain the same sign so it’s h(x-3)-2
