Best explained and correct answer gets

Measures of the angle of r, 31 s (x+4) t (3x+9)

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

What are linear equations? could'ya explain too me, ? ! and how do you see what graph is a proportional relationship?
