8(7c(2)+10+8r)
=(8)(7c(2)+10+8r)
=(8)(7c(2))+(8)(10)+(8)(8r)
=112c+80+64r
=112c+64r+80
~ Made a rough estimate, I'm sure you can work it out.
Answer:
The distance is 3.
Step-by-step explanation:
Since the x coordinates are the same, we take (-1)-(-4) = 3.
Factors of -8 that add up to 2: 4 & -2
(x + 4)(x - 2)
Set x to 0 for both and solve
x = -4
x = 2
