Use \\\\a^n + b^n = (a+b)(a^{n-1}b^0 - a^{n-2}b^1 + a^{n-3}b^2 - ... - a^1b^{n-2} + a^0b^{n-1}) \\--------------------------------\\\\\dfrac{x^n+y^n}{x+y}=\dfrac{(x+y)(x^{n-1}y^0-x^{n-2}y^1+x^{n-3}y^2-...-x^1y^{n-2}+x^0y^{n-1})}{x+y}\\\\=\boxed{x^{n-1}-x^{n-2}y+x^{n-3}y^2-...-xy^{n-2}+y^{n-1}}

Reduce the ratio to its lowest form 50:90
Aleonysh [2.5K]
5:9
You need to find the greatest common factor and divide each side by it.
In this case it is 10... 50/10 = 5   90/10 = 9

What is the sum of the angles of an octagon?
Pani-rosa [81]
Answer is 1080 degrees

Formula for calculating angles in a polygon (Shape with 4 or more sides) is (n-2) x 180, where n is the number of sides on the shape. Octagon has eight sides, so you subtract it by 2, which is 6. Multiply that by 180 to get 1080, which is the sum of the angles.
