2) 6

3) 8x^2-x-5

4) -6y

5) 10x^2+2

Step-by-step explanation:

hope this helps :)

• 4abc when a=2 b=3 c=-2

       4(2)(3)(-2)= -48

• 2xy-xyz when x=1, y=2, z=-1

       2×1×2-1×2×-1

• 3x^2+4x - 2+2x^2-x+2 +3x^2-4x-5= 3x^2+2x^2+3x^2(8x^2)-x-5        the 4x and -4x cancel each other out, same with -2 and +2
• probably because the 7's cancel each other out
• 3x^2+2x^2+5x^2+ (-7-2+7)
