Alot is in the shape of a triangle. the shorter leg measures 60 m. the hypotenuse is 20 m longer than the length of the longer leg. how long is the longer leg?

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
