B) 4(x+2) + 8(x-1)
first we distribute the 4
4x+ 8 + 8(x-1)
now we distribute the 8
4x+8 + 8x-8
now we combine the 4x and the 8x because they have the same variable so they are like terms
12x +8-8
the 8 cancels out so
b) 12x
now c)
3(w-5) - 6(w+2)
distribute 3
3w-15 - 6(w+2)
now distribute -6
3w-15 -6w -12
combine 3w and -6w because they are like terms
-3w -15-12
now combine -15 and -12
answer to c: -3w-27

Answer:
Step-by-step explanation:
1. (-4, -2) (4, 0)
(0 + 2)/(4 + 4)= 2/8= 1/4
2. (-1, 2) (1, -3) = (-3 - 2)/(1 + 1) = -5/2
3. (-2, 3) (0, 0) = (0 - 3)/(0 + 2) = -3/2
4. (1, 1) (3,2) = (2 - 1)/(3 - 1)= 1/2
