(n^4 - 1) = (n^2 - 1) (n^2 +1) = (n - 1) (n + 1) (n^2 + 1)
Answer:
Find the equation of the line perpendicular to x = 0 that passes through (-3,1)
Step-by-step explanation:
Using the equation, y - y1 = m(x - x1)
Since x = 0, the gradient, m = 0
Hence, y - 1 = 0
∴ y = 1
Answer:
33.9 m
Step-by-step explanation:
cos(32) = adjacent/hypotenuse
cos(32) = X/40
X = 40cos(32)
X = 33.92192385 m
Answer: 14+x=17
Step-by-step explanation:
when you do this you can put whatever letter you want but sum is adding so this is why it came out as it did
