Step-by-step explanation:

1.a) (-2a)+ (-8a)

= -10a

b)3x-2y+z+x+4y-3z

=4x+2y-2z

c)-xsquare+2x+2y+2

d)-5a+7b+7c

e)-a+5c

Answer 2

Answer:

1. (-2a) + (-8a) = -10a

2. (3x-2y+z) + (x+4y-3z)

= 3x+x -2y +4y-3z+z

= 4x+ 2y -2z

3. (x^2-2x+5y) + (-2x^2+4x-3y+2)

= -x^2+2x+2y+2

4. -5a+7b-7c

5. -a+4c
