I think it is 6n-8. But I could be wrong these are tricky to get. Good luck
Answer:
D
Step-by-step explanation:
First take out a factor of 2:
2(1 - 25x^2)
Then factor the difference of squares:
2(1 -5x)(1+5x)
Adding the coordinates of two points together and dividing them by two gives you back the midpoint of the segment.
i.e. the x coordinate for the midpoint is (-2+(-10))/2=-6
the y coordinate for the midpoint is (7+(-1))/2=3
Hence, the midpoint is (-6,3)
Answer:
Both the legs or sides are equal
GOOD LUCK FOR THE FUTURE! :)
Answer:
36.
Step-by-step explanation:
sec^2 (π/9) = 1 / cos^2 (π/9) = 1.13247
sec^2 (2π/9) = 1 / cos^2 (2π/9) = 1.70409
sec^2 (4π/9) = 1 / cos^2 (4π/9) = 33.1634
Adding these gives us 36 to the nearest whole number
