The distance walking a marathon at a constant speed is directly proportional to the time of walking. if jennifer walked 9 miles in 3 hours, how many miles will she walk in 5 hours at the same constant speed?

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
