ABC, the measure of C=90, the measure of A= 49, and BC=5.1 feet. Find the length of AB to the nearest tenth of a foot.

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
