Judah Meza · Answer 1

Answer: The values of A is - 3

Step-by-step explanation:

(x + 6y) - (3x - 10y)

distribute the negative to the second equation

x*-3x=-3x^2

x*10y=10xy

6y*-3x=-18xy

6y*10y=60y^2

take the end terms and create an equation

-3x^2+10xy-18xy+60y^2

combine like terms

-3x^2-8xy+60y^2~ final answer

-3 is the A term

-8 is the B term

60 is the C term

Kaylee · Answer 2

X+6y-3x+10y = Ax + By

-2x + 16y = Ax + By

A=-2

B=16
