Question

. Add the following using the horizontal method. a) 5xy + 2x, -2xy + 3y and 8xy - 3x + 4y b) m +1 and m2 + m c) 41+ 2+ +11, -31 + t and 4 - 2 d) 2a + 3b - 4c, 8c - 1 and 5b + 4​

Answer 1

Answer:

Step-by-step explanation:

$a)\ (5xy+2x)+(-2xy+3y)+(8xy-3x+4y)$

$5xy+2x-2xy+3y+8xy-3x+4y$

Arranging like terms

$5xy-2xy+8xy+2x-3x+3y+4y$

$11xy-x+7y$

$b)\ (m+1)+(m^2 +m)$

$m+1+m^2+m$

Arranging like terms

$m^2 +m+m+1$

$m^2+2m+1$

c) Question seems mistyped.

$d)\ (2a+3b-4c)+(8c-1)+(5b+4)$

$2a+3b-4c+8c-1+5b+4$

Arranging like terms

$2a+3b+5b-4c+8c-1+4$

$2a+8b+4c+3$

Answer 2

Answer:

Step-by-step explanation:

Question: a) 5xy + 2xy + 3y and 8xy - 3x + 4y

Answer: = = 13y - x + 5y

d) 2a + 3b - 4c, 8c - 1 and 5b + 4​

Answer: 2a + 3b -4c + 8c - 1 + 5b + 4

2a + 3b+ 5b - 4c + 8c - 1 +4

2a + 8b + 4c + 3

That's what I could find, sorry for this two because I know only the answer for these both, sorry, looking more questions and hope you help me too!!!
